Product Overview

The UC2525AN 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 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
