The SDC7500 is a voltage mode pulse width modulation switching regulator control circuit designed primarily for power supply control. The SDC7500 consists of a reference voltage circuit, two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, and an output control circuit. The precision of voltage reference (VREF) is ±1% through trimming and this provides a better output voltage regulation. The SDC7500 provides for push-pull or single-ended output operation, which can be selected through the output control.






1. Complete PWM power control circuitry

2. Uncommitted outputs for 200mA sink or source current

3. Output control for single ended or push pull operation

4. Internal regulator provides a stable 5V reference supply with 5% tolerance

5. Adjustable dead-time control
