Description

The UC1525A/1527A series of pulse width modulator integrated circuits are designed tooffer improved performance and lowered external parts count when used in designing all types ofswitching power supplies. The on-chip 5.1-V reference is trimmed to 1% and the input common-moderange of the error amplifier includes the reference voltage, eliminating external resistors. A syncinput to the oscillator allows multiple units to be slaved or a single unit to be synchronized toan external system clock. A single resistor between CT and the dischargeterminals provides a wide range of dead-time adjustment. These devices also feature built-insoft-start circuitry with only an external timing capacitor required. A shutdown terminal controlsboth the soft-start circuitry and the output stages, providing instantaneous turn off through thePWM latch with pulsed shutdown, as well as soft-start recycle with longer shutdown commands.

Feature

  • 8-V to 35-V Operation
  • 5.1-V Reference Trimmed to 1%
  • 100-Hz to 500-kHz OscillatorRange
  • Separate Oscillator Sync Terminal
  • AdjustableDead-Time Control
  • Internal Soft Start
  • Pulse-by-PulseShutdown
  • Input Undervoltage Lockout WithHysteresis
  • Latching PWM to Prevent Multiple Pulses
  • DualSource and Sink Output Drivers
