  • EXTERNAL COMPONENTS INFORMATION Input Capacitor (CIN, CBIAS) Connect an input capacitor (CBIAS) of 1 µF or more between the VBIAS pin and the GND pin at the shortest distance. Also, connect an input capacitor (CIN) of 1 µF or more between the VIN pin and the GND pin at the shortest distance. It is recommended to use a ceramic capacitor of 6.3 V or more such as X5R or X7R having small temperature dependence to ESR, ESL, and capacitance. Output Capacitor(COUT) Phase compensation is provided to secure stable operation even when the load current is varied. Connect a capacitor(COUT) of 2.2 µF or more but less than 100µF between the VOUT pin and the GND pin closely. We recommend to use ceramic capacitors with very low ESR and ESL and good temperature characteristics such as X5R or X7R type. Besides, set for the output capacitor to ensure the following effective capacitance in consideration of the dependence of temperature, DC bias, and package size.

  • Enable Function Forcing above designated "High" voltage to EN pin, the NR1620 becomes active. Forcing below designated "Low" voltage to EN pin shuts down the NR1620. Products with a discharge function (NR1620xxxxxA) turn on the discharge FET in the shutdown state to discharge the output capacitor (COUT). Products without a discharge function (NR1620xxxxxB) discharge the charge of the output capacitor (COUT) in the load circuit in the shutdown state. When the EN pin is OPEN, the NR1620 is in an undefined state because it is not pulled up or down internally. If control by the EN pin is not possible or is not required, connect the EN pin to the VBIAS pin, etc., so that "High" is input at start-up. In case of the EN pin is connected to the VBIAS pin, the built-in FET for discharge is not expected to work properly. Even if voltage is applied to the EN pin before the VBIAS and VIN pins, it will not result in IC failure.
  • Discharge Function (NR1620xxxxxA) This function turns on the FET connected between the VOUT pin and GND pin to discharge the charge stored in the output capacitor (COUT) and quickly reduce the output voltage to near 0 V. This function is enabled when the EN pin is "Low". This function is effective when the Bias supply voltage(VBIAS) is within the recommended operating conditions. Please note that when the EN input voltage and the VBIAS Input voltage (VBIAS) are used in common, the COUT charge cannot be discharged sufficiently when the VBIAS Input voltage (VBIAS) drops.
  • Under Voltage Lockout Circuit(UVLO) The UVLO function is an auxiliary function that stops the operation of the IC, when the input voltage(VIN) is low(typ:under 0.35 V) and the IC cannot operate normally. In versions with a discharge function, the output pin is pulled down by the discharge FET when this function works. To restart the operation, the input voltage (VIN) must be higher than 0.5V. This function is effective when the bias input voltage (VBIAS) is within the recommended operating condition.
  • Current limit function at startup This function limits the inrush current at startup (IRUSH), which is the sum of the charge current(ICHG) to the output capacitor (COUT) and the load current (ILOAD), by the startup current limit (ILIMRISE, Typ. 75 mA). The inrush current at startup (IRUSH) is defined by the following formula. IRUSH = ICHG + ILOAD ICHG: Charge current to output capacitors. ILOAD: Load current With an output capacitor (COUT, more than 75 uF/VSET) and load current (ILOAD) such that this inrush current value at startup (IRUSH) reaches the startup current limit (ILIMRISE, Typ. 75 mA), the output voltage rises at a slope determined by the output current limit at startup (ILIMRISE). The rise time (tON) due to the inrush current limiting function can be determined by the following formula. tON = tD1 + COUT × VSET / ILIMRISE tD1: Delay Time at Start-up Typ. 880 μs COUT: Effective capacitance value of output capacitor
  • 11 - Ver.1.1 VSET: Set Output Voltage ILIMRISE: Current Limit at Start-up Typ. 75 mA The start-up current limit (ILIMRISE) is in effect until 4.2 ms (typ.) after EN start-up. After that, the output current limit (ILIM, Typ. 240 mA) and the short-circuit current (ISC, Typ. 110 mA) protect against overcurrent. To enable the inrush current limit function, apply the recommended operating conditions (VSET + 1.4V, Min. 2.4V or more) as the bias input voltage (VBIAS) and then input "High" to the EN pin to activate it. If "High" is input to the EN pin while the bias input voltage (VBIAS) does not match the recommended operating conditions, the NR1620 may start up without the inrush current limit function enabled. If the load current (ILOAD) exceeds the start-up current limit (ILIMRISE) during start-up, the output voltage (VOUT) will not reach the set output voltage (VSET). The UVLO function is active during output voltage start-up. This protection function may work when the IC starts up with load current or when a large output capacitor (COUT) is connected. In such cases, adjust the output capacitor (COUT) or startup timing to reduce the inrush current. VEN VOUT tD1 ILIMRISE VEN≤VENL IIN Ramp-up Time with Current Limit Function COUT×VSET / ILIMRISE VEN≥VENH VSET COUT > 75 μF /VSET
  • Automatic Mode Switching Function The automatic mode switching feature can improve battery life, especially in battery-powered applications with long-cycle intermittent operation. NR1620 has two modes: fast mode and low power mode. Fast mode is a mode with high current consumption for fast transient response. Low power mode achieves lower current consumption, although in this mode transient response becomes slower compared to the Fast mode. When the load current (ILOAD) exceeds the fast mode switching current (IOUTH), it switches to fast mode, and when it falls below the low power mode switching current (IOUTL), it switches to low power mode. Switching currents (IOUTH, IOUTL) have hysteresis and they will never be equal. Output voltage may have difference between fast mode and low power mode. For details, refer to " Output Voltage Difference between Modes" in the Electrical Characteristics. VOUT ILOAD MODE Low Power Mode Low Power Mode IOUTH IOUTL Fast Mode ΔVOUT
