Overview

Description
The UC1524A family of regulating PWM ICs offers enhanced features compared to the industry-standard UC1524. It retains the versatile architecture while addressing limitations. The UC1524A is pin-compatible with non-A models and can be directly interchanged in most applications without affecting power supply performance.

Features
Precision reference internally trimmed to ±1%
Under-voltage lockout with hysteretic turn-on
Start-up supply current less than 4mA
Output current to 200mA, 60V output capability
Wide common-mode input range for error and current limit amplifiers
PWM latch ensures single pulse per period
Double pulse suppression logic
200ns shutdown through PWM latch
Ensured frequency accuracy
Thermal shutdown protection

Applications
The UC1524A family is suitable for various applications, including:
Switching power supplies
DC-DC converters
Motor control
Battery chargers
Lighting control
