UC2525AJ Texas Devices REGULATING PULSE WIDTH

The UC1525A/1527A assortment of pulse width modulator built-in circuits are designed to produce improved effectivity and lowered exterior components rely when utilized in designing all kinds of switching power gives. The on-chip 5.1-V reference is trimmed to 1% and the enter common-mode fluctuate of the error amplifier accommodates the reference voltage, eliminating exterior resistors. A sync enter to the oscillator permits quite a few fashions to be slaved or a single unit to be synchronized to an exterior system clock. A single resistor between CT and the discharge terminals affords a range of dead-time adjustment. These devices moreover attribute built-in soft-start circuitry with solely an exterior timing capacitor required. A shutdown terminal controls every the soft-start circuitry and the output ranges, providing instantaneous flip off by way of the PWM latch with pulsed shutdown, along with soft-start recycle with longer shutdown directions.
