A DC voltage within the range of 2.4V to 5.5V will inhibit the oscillator. 2CT Timing capacitor CT connects pin to ground setting oscillator frequency. 3RT Resistor RT connects to ground setting the charge current for CT. Its value must be between 4.0k Ω and 16kΩ. 4VFB 1 The inverting input of error amplifier 1. Normally it is connect- ed to the switching power supply output. 5 COMP1 The output of error amplifier 1, for loop compensation. 6 SENSE1 Output 1 pulse by pulse current limit. 7VOUT 1 Drives the power switch at output 1. 8 Gnd Logic ground 9 Pwr Gnd Power ground. Power device return is connected to this pin. 10 VOUT 2 Drives the power switch at output 2. 11 SENSE2 Output 2 pulse by pulse current limit. 12 COMP2 Output of error amplifier 2, for loop compensation. 13 VFB 2 Inverting input of error amplifier 2. Normally it is connected to the switching power supply output. 14 ENABLE2 Output 2 disable. A logic low at this pin disables VOUT 2. 15 VREF 5.0V reference output. It can source current in excess of 30mA. 16 VCC The positive supply of the IC. The minimum operating voltage after start-up is 8.8V. |
