Rochester Electronics PMIC - Voltage Regulators - DC DC Switching Controllers UC2525AJ

The UC2525AJ is a pulse width modulator integrated circuit designed for use in various switching power supply applications. It operates within an input voltage range of 8 V to 35 V and features a trimmed 5.1 V reference with 1% accuracy. The device supports an oscillator frequency range from 100 Hz to 500 kHz and includes a synchronization input for slaving multiple units or synchronizing to an external clock. Key features include adjustable dead-time control, built-in soft-start circuitry requiring only an external timing capacitor, and a shutdown terminal that allows for both instantaneous turn-off and soft-start recycling. The UC2525AJ is suitable for applications such as off-line and DC/DC power supplies, voltage mode converters, solar inverters, welding inverters, motor control, and battery chargers. It is available in multiple package types, including CDIP and PDIP, with an operating temperature range of -25 ¬8C to 85 ¬8C.
