Description
The UC1524A family of regulating PWM ICs has been designed to retain the
same highly versatile architecture of the industry standard UC1524 (SG1524)
while offering substantial improvements to many of its limitations. The
UC1524A is pin compatible with “non-A” models and in most existing
applications can be directly interchanged with no effect on power supply
performance. Using the UC1524A, however, frees the designer from many
concerns which typically had required additional circuitry to solve.
The UC1524A 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
