www.sii-ic.com STEP-UP, SUPER-SMALL PACKAGE, 600 kHz, PWM CONTROL o r PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER © SII Semiconductor Corporation, 2002-2015 Rev.8.1_01 The S-8355/56/57/58 Series is a CMOS step-up switching regulator controller whic h mainly consists of a reference voltage source, an oscillation circuit, an error amplifier, a phase com pensation circuit, a PWM control circuit (S-8355/57 Series) and a PWM/PFM switching control circuit (S-8356/58 Series). With an external low-ON-resistance Nch Power MOS, this produc t is ideal for applications requiring high efficiency and a high output current. The S-8355/57 Series realizes low ripple, high efficiency, and ex cellent transient characteristics due to its PWM control circuit whose duty ratio can be varied linearly from 0 to 83% (from 0 to 78% for 250 kHz, 300 kHz, and 600 kHz models), an excellently designed error amplifier and a phase compensation circuits. S-8356/58 Series features a PWM/PFM switch ing controller that can sw itch the operation to a PFM controller with a duty ratio is 15% under a light load to prevent a decline in the efficiency due to the IC operating current.  Features

• Low voltage operation : Startup at 0.9 V min. (IOUT = 1 mA) guaranteed
• Low current consumption : During operation 25.9 μA (3.3 V, 100 kHz, typ.) During shutdown 0.5 μA (max.)
• Duty ratio : Built-in PWM/PFM switching control circuit (S-8356/58 Series) 15 to 83% (100 kHz models) 15 to 78% (250 kHz, 300 kHz, and 600 kHz models)

1.1 PWM Control (S-8355/57 Series)

The S-8355/57 Series is a DC-DC converter using a pu lse width modulation method (PWM) and features a low current consumption. In conventional PFM DC-DC converters, pulses are skip ped when the output load current is low, causing a fluctuation in the ripple frequency of the output voltage, resulting in an increase in the ripple voltage. The switching frequency does not change, although the pulse width changes from 0 to 83% (78% for F, G, H, J, L, M, N, P and Q types) corresponding to each load current. The ripple voltage generated from switching can thus be removed easily through a filter because the switching frequency is constant.

1.2 PWM/PFM Switching Control (S-8356/58 Series)

S-8356/58 Series is a DC-DC converter that automatical ly switches between a pulse width modulation method (PWM) and a pulse frequency modulation method (PFM), depending on the load current, and features low current consumption. The S-8356/58 Series operates under PWM control with the pulse width duty changing from 15 to 83% (78% for F, G, H, J, L, M, N, P and Q types) in a high output load current area. The S-8356/58 Series operates under PFM control with the pulse width duty fixed at 15%, and pulses are skipped according to the load current. The oscillation circuit thus oscillates intermittently so t hat the resultant lower self current consumption prevents a reduction in the efficiency at a low load current. The switching point from PWM control to PFM control depends on the external devices (coil, diode, etc.), input voltage and output voltage. This series are an especially highly efficient DC-DC converter at an output current around 100 μA. 2. Soft Start Function For this IC, the built-in soft start circuit controls the rush current and overshoot of the output voltage when powering on or when the OFF/ON pin is switched to the “H” level.

OFFON/ Pin (Shutdown Pin) (SOT-23-5 P ackage Products of S-8355/56/57/58 Series B, H, F, K, L, M, N and Q Types) OFF/ON pin stops or starts step-up operation. Setting the OFF/ON pin to the “L” level stops operation of all the internal circuits and reduces the current consumption significantly. DO NOT use the OFF/ON pin in a floating state because it has the structure shown in Figure 13 and is not pulled up or pulled down internally. DO NOT apply a voltage of between 0.3 V and 0.75 V to the OFF/ON pin because applying such a voltage increases the current consumption. If the OFF/ON pin is not used, connect it to the VOUT pin. The OFF/ON pin does not have hysteresis. Table 23 OFF/ON pin CR oscillation circuit Output voltage “H” Operation Fixed “L” Stop ≅VIN*1 *1.

When M1 is turned OFF (t OFF), the energy stored in L is emitted through a diode to the output capacitor. Then, the reverse voltage (VL) is generated : VL = (VOUT + VD*1) − VIN (5) *1.

STEP-UP, SUPER-SMALL PACKAGE, 600 kHz, PWM CONTROL or PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER S-8355/56/57/58 Series Rev.8.1_01 Integration of the equation (6) is as follows : tL VVVII INDOUT PKL •  −+−= (7) During tON, the energy is stored in L and is not transmitted to VOUT. When receiving the output current (IOUT) from VOUT, the energy of the capacitor (CL) is consumed. As a result, the pin voltage of CL is reduced, and goes to the lowest level after M1 is turned ON (tON). When M1 is turned OFF, the energy stored in L is transmitted through the diode to CL, and the voltage of CL rises rapidly. VOUT is a time function, and therefore indicates the maximum value (ripple voltage (VP−P) ) when the current flowing through into VOUT and load current (IOUT) match. Next, the ripple voltage is determined as follows.

Capacitor (CIN, CL) A capacitor on the input side (C IN) improves the efficiency by reducing the power impedance and stabilizing the input current. Select a CIN value according to the impedance of the power supply used. A capacitor on the output side (C L) is used for smoothing the output voltage. For step-up types, the output voltage flows intermittently to the load current, so step-up types need a larger capacitance than step-down types. Therefore, select an appropriate capacitor in accordance with the ripple voltage, which increases in case of a higher output voltage or a higher load current. The capacitor value should be 10 μF or more. Select an appropriate capacitor the equivalent series resistance (R ESR) for stable output voltage. The stable voltage range in this IC depends on the R ESR. Although the inductance value (L value) is also a factor, an R ESR of 30 to 500 mΩ maximizes the characteristics. However, the best R ESR value may depend on the L value, the capacitance, the wiring, and the applications (output load). Therefore, fully evaluate the R ESR under the actual operating conditions to determine the best value. Refer to the “3. Example of Ceramic Capacitor Application ” (Figure 26 ) in the “ Application Circuit ” for the circuit example using a ceramic capacitor and the external resistance of the capacitor (RESR). 4. External Transistor An enhancement (N-channel) MOS FET type or A bipolar (NPN) type can be used as the external transistor.

Figure 17 Circuit Example Using MOS FET (N-channel) Type An N-channel power MOS FET should be used for the MOS FET. Because the gate voltage and current of the external power MOS FET are supplied from the stepped-up output voltage (V OUT), the MOS FET is driven more effectively. A large current may flow during startup, depending on the MOS FET selection. So perform sufficient evaluation using the actual devices. Also recommend to use a MOS FET with an input capacitance of 700 pF or less. Since the ON-resistance of the MOS FET might depend on the difference between the output voltage (V OUT) and the threshold voltage of the MOS FET, and affect the output current as well as the efficiency, the threshold voltage should be low. When the output voltage is low, the circuit operates only when the MOS FET has a threshold voltage lower than the output voltage.

A circuit example using the CPH3210 (h FE = 200 to 560) from Sanyo Electric Co., Ltd. As a bipolar transistor (NPN) is shown in Figure 19 to 24 in the “ Standard Circuits ”. The hFE value and R b value of the bipolar transistor determine the driving capacity to increase the ou tput current using a bipolar transistor. A peripheral circuit example of the transistor is shown in Figure 18. Nch Pch VOUT*1 IPK EXT Cb 2200 pF Rb 1 kΩ *1. VDD for E, G, J, K, L, M, P and Q types. Figure 18 External Transistor Peripheral Circuit The recommended Rb value is around 1 k Ω. Actually, calculate the necessary base current (I b) from the bipolar transistor (hFE) using FE PK b h II = , and select the smaller Rb value than EXTHb OUT b I 4.0 I 7.0VR −−= *1. A small Rb value can increase the output current, but the efficiency decreases. Since a current may flow on the pulse and the voltage may drop due to wiring resistance or other factors in the actual circuit, therefore the optimum R b value should be determined by experiment. Connecting the speed-up capacitor (C b) in parallel with the R b resistance as shown in Figure 18 , decreases switching loss and improves the efficiency. The Cb value is calculated according to 7.0fRπ2 oscb b

VDD / VOUT Separate Type (For E, G, J, K, L, M, P and Q Types) The E, G, J, K, L, M, P and Q types provides separate internal circuit power supply (VDD pin) and output voltage setting pin (VOUT pin) in the IC, making it ideal for the following applications.

This IC starts a step-up operation at V DD = 0.8 V, but set 1.8 ≤ VDD ≤ 10 V to stabilize the output voltage and frequency of the oscillator. (Input a voltage of 1.8 V or more at the VDD pin for all products with a setting less than 1.9 V.) An input voltage of 1.8 V or more at the VDD pin allows connection of the VDD pin to either the input voltage VIN pin or output VOUT pin. 2. Choose external resistors R A and RB so as to not affect the output voltage, considering that there is impedance between the VOUT pin and VSS pin in the IC chip. The internal resistance between the VOUT pin and VSS pin is as follows : (1) S-835xx18 : 2.1 to 14.8 MΩ (2) S-835xx20 : 1.4 to 14.8 MΩ (3) S-835xx30 : 1.4 to 14.2 MΩ (4) S-835xx50 : 1.4 to 12.1 MΩ 3.
