Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Input supply to the startup regulator with operating input range of 13V to 100V and transient capability to 105V. |
| 2 | COMP1 | input | PWM control input for Controller 1 providing voltage feedback to PWM comparator through 3:1 divider with internal 5-kΩ pull-up resistor to 5.0V for opto-coupler bias. |
| 3 | CS1 | input | Current sense input for Controller 1 for current mode control and cycle-by-cycle current limiting with 0.5V threshold, maximum voltage 1.25V. |
| 4 | SS1 | input | Soft-start input for Controller 1 with internal 50-µA charging current source, reduced to 1-µA during current limit restart, shutdown when forced below 0.5V. |
| 5 | UVLO | input | VIN under-voltage lockout input with 1.25V comparator reference, switched 20-µA current source for hysteresis, and controls maximum duty cycle. |
| 6 | VCC | power_out | Startup regulator output providing 7.7V regulated supply with current limit minimum of 19mA. |
| 7 | OUT1 | output | Main gate driver output for Controller 1 switching between VCC and GND1 at frequency equal to half oscillator frequency. |
| 8 | GND1 | power_in | Ground connection for Controller 1 including gate driver, PWM controller, soft-start and support functions. |
| 9 | GND2 | power_in | Ground connection for Controller 2 including gate driver, PWM controller and soft-start. |
| 10 | OUT2 | output | Main gate driver output for Controller 2 switching between VCC and GND2 at frequency equal to half oscillator frequency. |
| 11 | RES | input | Hiccup mode restart adjust input with external capacitor setting time delay before forced restart during sustained current limiting, threshold at 2.55V. |
| 12 | SS2 | input | Soft-start input for Controller 2 with internal 50-µA charging current source, reduced to 1-µA during current limit restart, shutdown when forced below 0.5V. |
| 13 | CS2 | input | Current sense input for Controller 2 for current mode control and cycle-by-cycle current limiting with 0.5V threshold, maximum voltage 1.25V. |
| 14 | COMP2 | input | PWM control input for Controller 2 providing voltage feedback to PWM comparator through 3:1 divider with internal 5-kΩ pull-up resistor to 5.0V for opto-coupler bias. |
| 15 | DCL | input | Duty cycle limit input with external resistor setting maximum allowed duty cycle at OUT1 and OUT2. |
| 16 | RT/SYNC | input | Oscillator frequency adjustment and synchronization input with external resistor setting oscillator frequency and accepting ac-coupled external synchronization pulses. |
