The UC3524ADW is a Pulse Width Modulation (PWM) has been designed to retain the same highly versatile architecture of the industry standard while offering substantial improvements to many of its limitations. It is pin compatible with "non-A" models and in most existing applications can be directly interchanged with no effect on power supply performance. Using this however, frees the designer from many concerns which typically had required additional circuitry to solve. It includes a precise 5V reference trimmed to ±1% accuracy, eliminating the need for potentiometer adjustments; an error amplifier with an input range which includes 5V, eliminating the need for a reference divider; a current sense amplifier useful in either the ground or power supply output lines and a pair of 60V, 200mA uncommitted transistor switches which greatly enhance output versatility.
Fully interchangeable with standard UC1524 family
Precision reference internally trimmed to ±1%
High-performance current limit function
Under-voltage lockout with hysteretic turn-on
<=4mA Start-Up supply current
Wide common-mode input range for both error and current limit amplifiers
