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.
