DUAL SOURCE/SINK OUTPUT DRIVERS DIP16 16(Narrow) DESCRIPTION The SG3525Aseries 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 betweenthe CT andthe dischargeterminals provide a wide range of d...
