SG 3525 PWM CONTROLLER IC  NARROW SOP-16

DESCRIPTION
The 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 + 5.1 V 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. These devices also feature built-in soft-start circuitry with only an external
timing capacitor required. A shutdown terminal controls both the soft-start circuitry and the output stages,
providing instantaneous.
