Introduction
The UCC3588 synchronous buck regulator provides precise, high-efficiency power conversion. Using a minimal number of external components, the UCC1588 converts 5V to an adjustable output ranging from 3.5 VDC to 2.1 VDC in 100 mV steps, and from 2.05 VDC to 1.3 VDC in 50 mV steps, with 1% DC system accuracy. High integration and innovative design enable this 16-pin controller to deliver a complete control solution for today's demanding microcontroller power requirements. Typical applications include onboard or VRM-based power conversion for Intel Pentium II microprocessors and other processors from various manufacturers. High efficiency is achieved through synchronous rectification.
The soft-start function provides controlled rise of the system output voltage. The overcurrent circuit detects hard (or soft) short circuits on the system output voltage and triggers a timed soft-start/shutdown cycle to reduce the PWM controller's on-time to 5%.
Oscillator frequency is externally programmed via RT, operating over a range of 50 kHz to 800 kHz. The gate drivers are low-impedance totem-pole output stages capable of driving high-power external MOSFETs. Cross-conduction is eliminated by inserting fixed dead times between turn-off and turn-on of the external high-side and synchronous MOSFETs. The device incorporates an undervoltage lockout circuit to ensure correct logic states at the outputs during power-up and power-down.
This device is available in 16-pin SMT, plastic and ceramic DIP, and TSSOP packages. The UCC3588 operates over a temperature range of 0℃ to 70℃.
