UC2525AN +BOM

Handles complex switching controller operations with ease

UC2525AN General Description

The UC1525A/1527A series of pulse width modulator integrated circuits present a compelling option for designing switching power supplies with enhanced performance and reduced external components. With a precision trimmed 5.1-V reference voltage and an error amplifier boasting a wide input common-mode range that includes the reference voltage, the need for external resistors is eliminated. Additionally, the sync input feature allows for synchronization of multiple units or integration with an external system clock. An adjustable dead-time range is conveniently provided by a single resistor between CT and the discharge terminals. Furthermore, these devices are equipped with built-in soft-start circuitry, requiring only an external timing capacitor for operation. The shutdown terminal offers control over both the soft-start circuitry and the output stages, enabling instant turn off through the PWM latch with pulsed shutdown. The soft-start recycle function can also be activated with longer shutdown commands, adding to the flexibility and convenience of these integrated circuits
