SG3525AP STMICROELECTRONICS PWM Controller, 35V-8V supply, 500 kHz, 500mA out, NSOIC-16

SG3525AP STMICROELECTRONICS PWM Controller, NSOIC-16

The SG3525AP series of pulse width modulator integrated circuits are designed to offer improved performance and lowered external parts count when used in designing all types of switching power supplies. The on-chip reference is trimmed to ± 1 % and the input common-mode range of the error amplifier includes the reference voltage eliminating external resistors. A sync input to the oscillator allows multiple units to be slaved or a single unit to be synchronized to an external system clock. A single resistor between the CT and the discharge terminals provide a wide range of dead time adjustment.
