No. EA-415-251006 THEORY OF OPERATION Soft-start Time Starting-up with CE Pin The IC starts to operate when the CE pin voltage (VCE) exceeds the threshold voltage. The threshold voltage is preset between CE “H” input voltage (VCEH) and CE “L” input voltage (VCEL). After the start-up of the IC, soft- start circuit starts to operate. Then, after a certain period of time, the reference voltage (VREF) in the IC gradually increases up to the specified value. Switching starts when VREF reaches the preset voltage, and after that the output voltage rises accompanying V REF’s increase. Soft-start time (tSTART) starts when soft -start circuit is activated, and ends when the reference voltage reaches the specified voltage. Soft start time is not always equal to the turn-on speed of the DC/DC converter. Note that the turn-on speed could be affected by the power supply capacity, the output current, the inductance value and the COUT value.

(VLX) Depending on Power Supply, Load Current, External Components (VOUT) Output Voltage CE Pin Input Voltage Timing Chart: Starting-up with CE Pin Starting-up with Power Supply After the power-on, when VIN exceeds the UVLO released voltage (V UVLOR), the IC starts to operate. Then, soft-start circuit starts to operate and after a certain period of time, VREF gradually increases up to the specified value. Switching starts when V REF reaches t he preset voltage, and after that the output voltage rises accompanying VREF’s increase. Soft-start time starts when soft-start circuit is activated, and ends when V REF reaches the specified voltage. Note that the turn-on speed of V OUT could be affected by the power supply capacity, the output current, the inductance value, the COUT value and the turn-on speed of VIN determined by CIN.

No. EA-415-251006 Undervoltage Lockout (UVLO) Circuit If the VIN becomes lower than the UVLO detector threshold (VUVLOF), the UVLO circuit starts to operate, VREF stops, and P-channel and N-channel built-in switch transistors turn “OFF”. As a result, VOUT drops according to the COUT capacitance value and the load. To restart the operation, VIN needs to be higher than VUVLOR. Overvoltage Protection (OVP) Circuit If the VOUT becomes higher than the OVP detector threshold (VOVP), the OVP circuit starts to operate, P-channel and N-channel built-in switch transistors turn “OFF”. As a result, VOUT drops according to the COUT capacitance value and the load. Overcurrent Protection Circuit Overcurrent protection circuit supervises the inductor peak current (the peak current flowing through Pch Tr (SW1) in each switching cycle, and if the current exceeds the BULX current limit (I LXLIM), it turns off Pch Tr (SW1).

No. EA-415-251006 VFM Mode The VFM (Variable Frequency Modulation) mode is adopted as a switching method to achieve a high efficiency under light load conditions. A switching frequency varies depending on values of input voltage (V IN), output voltage (VOUT), and output current (IOUT). Check the actual characteristics to avoid the switching noise. A switching starts when VOUT drops below the lower-limit reference voltage (VREFL). When VOUT exceeds the upper-limit reference voltage (V REFH), a constant voltage is output by a hysteresis control which stops the switching. In order to operate within the rated characteristic of inductor and avoid the deteriorated band frequency of DC superimposed characteristics, when the inductor current (I L) exceeds LX current limit (I LXLIM), the operation shifts to off-cycle. And when IL drops below the valley current limit (ILXVAL), the operation shifts to on-cycle.

No. EA-415-251006 TECHNICAL NOTES The performance of a power source circuit using this device is highly dependent on a peripheral circuit. A peripheral component or the device mounted on PCB should not exceed a rated voltage, a rated current or a rated power. When designing a peripheral circuit, please be fully aware of the following points. Refer to PCB Layout below.

• Use ceramic capacitors with a low equivalent series resistance (ESR), considering the bias characteristics and input/ output voltage.
• When the built-in switches are turned off, the inductor may generate a spike-shaped high voltage. Use the high-breakdown voltage capacitor (C OUT) which output voltage is 1.5 times or more than the set output voltage.
• Use an inductor that has a low DC resistance, has an enough tolerable current and is less likely to cause magnetic saturation. If the inductance value is extremely small, the peak current of LX may increase. When the peak current of LX reaches to the LX limit current (ILXLIM), overcurrent protection circuit starts to operate. When selecting the inductor, consider the peak current of LX pin (ILXMAX).
• When an intermediate voltage other than V IN or GND is input to the CE pin, a supply current may be increased with a through current of a logic circuit in the IC. The CE pin is neither pulled up nor pulled down, therefore an operation is not stable at open. RP604Zxx1x-E2-F is discontinued product.
