UC2525ADW - TI Function Overview

The UC2525ADW is a Pulse Width Modulation (PWM) designed to offer improved performance and lowered external parts count when used in designing all types of switching power supplies. The on-chip 5.1V reference is trimmed to ±1% and the input common-mode range of the error amplifier includes the reference voltage, eliminating external resistors. A sync input to the oscillator allows multiple units to be slaved or a single unit to be synchronized to an external system clock. A single resistor between the CT and the discharge terminals provides a wide range of dead-time adjustment. It also feature built-in soft-start circuitry with only an external timing capacitor required. A shutdown terminal controls both the soft-start circuitry and the output stages, providing instantaneous turn off through the PWM latch with pulsed shutdown, as well as soft-start recycle with longer shutdown commands.
Separate oscillator sync terminal
Adjustable deadtime control
Internal soft-start
Pulse-by-pulse shutdown
Input under-voltage lockout with hysteresis
Latching PWM to prevent multiple pulses
Dual source/sink output drivers
Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
