Characteristic Unit Max Typ Min Test Conditions Power Good Output PWRGD Sink Current VFB = 1.7 V, VPWRGD = 1.0 V 0.5 4.0 15 mA PWRGD Upper Threshold % of Nominal DAC Code 5.0 8.5 12 % PWRGD Lower Threshold % of Nominal DAC Code −12 −8.5 −5.0 % PWRGD Output Low Voltage VFB = 1.7 V, IPWRGD = 500 μA − 0.2 0.3 V Overvoltage Protection (OVP) Output OVP Source Current OVP = 1.0 V 1.0 10 25 mA OVP Threshold % of Nominal DAC Code 5.0 8.5 12 % OVP Pull−Up Voltage IOVP = 1.0 mA, VCC − VOVP − 1.1 1.5 V General Electrical Specifications VCC Monitor Start Threshold − 7.9 8.4 8.9 V VCC Monitor Stop Threshold − 7.6 8.1 8.6 V Hysteresis Start−Stop 0.15 0.3 0.6 V VCC Supply Current No Load on GATE(H), GATE(L) − 12 20 mA PACKAGE PIN DESCRIPTION PACKAGE PIN # PIN SYMBOL FUNCTION SO−16 1, 2, 3, 4, 6 VID0−VID4 Voltage ID DAC inputs. These pins are internally pulled up to 5.65 V if left open. VID4 selects the DAC range. When VID4 is high (logic one), the Error Amp reference range is 2.125 V to 3.525 V with 100 mV increments. When VID4 is low (logic zero), the Error Amp reference voltage is 1.325 V to 2.075 V with 50 mV increments. 5 VREF Bandgap Reference Voltage. It can be used to generate other regulated output voltages. 7 VFB Error amp inverting input, PWM comparator non−inverting input, current limit comparator non−inverting input, PWRGD and OVP comparator input. 8 VOUT Current limit comparator inverting input. 9 VCC Input power supply pin for the internal circuitry. Decouple with filter capacitor to GND. 10 GATE(H) High side switch FET driver pin. 11 GND Ground pin. 12 GATE(L) Low side synchronous FET driver pin. 13 OVP Overvoltage protection pin. Goes high when overvoltage condition is detected on VFB. 14 PWRGD Power Good Output. Open collector output drives low when VFB is out of regu- lation. 15 COFF Off−Time Capacitor pin. A capacitor from this pin to GND sets the off time for the regulator. 16 COMP Error amp output. PWM comparator inverting input. A capacitor to GND pro- vides error amp compensation. |
