Product Introduction

UC2573 step-down pulse-width modulator step-down regulator

illustrate

Barker's UC3573 is a pulse-width modulation of which steps regulate the positive input voltage. The chip is optimized for the use of an external PMOS switch in a single-inductance buck switching converter. The block plot consists of a high-precision reference, voltage mode operation of the error amplifier, an oscillator, a PWM comparator with latching logic, and a 0.5A peak gate driver configuration. The UC3573 includes an undervoltage lockout circuit to ensure sufficient input supply voltage in the presence of a pulse current limit for one pulse before any conversion activity can occur. The input current can be felt and is limited to determining the maximum value for the user. In addition, the sleeping UVLO comparator interface circuit, when turned on and off, has an input voltage lower than the UVLO threshold chip.
