The SDC7500 incorporates all the functions required in the construction of a pulse-width modulation switching circuit. Designed primarily for switching power supply control, it offers the systems engineer the flexibility to tailor control circuitry to its own application.
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 deadtime control
1. PC power supply
2. DC-DC convertor
