UC3525A

• Product Introduction

The UC1525A/1527A series of pulse width modulators are designed to provide higher performance and reduce the number of external components when designing for all types of switching power supplies. The on-chip 5.1 V reference needs to be trimmed to ± 1%, and the range of input common-mode error amplifiers includes reference voltages without the need for external resistors. Synchronous input to oscillator allows multiple units to be synchronized to an external system clock in a slave or one unit. The adjustment of the individual resistor at the launch terminal in C T and time provides a wide range of dead. The devices also have built-in soft-start with only one external timing circuit capacitance requirement.
