SG3525 Overview
Key Specifications
Package: SOP
Mount Type: Surface Mount
Pins: 16
Max Voltage (typical range): 35 V
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.
Key Features
- of these PWM circuits is a latch following the comparator
- Once a PWM pulses has been terminated for any reason, the outputs will remain off for the duration of the period
- The latch is reset with each clock pulse
- The output stages are totem-pole designs capable of sourcing or sinking in excess of 200 mA
- The SG3525Aoutputstage features NOR logic, giving a LOW output for an OFF state
