55 V, 1.4 MHz Synchronous 4-Switch Buck-Boost Controller with Spread Spectrum

Overview

TopologyBuck-Boost Converter
Input voltage4-55 V
Switching frequency600-1400 kHz
Output 155 V

Description

The ADPL76030 evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the features of the ADPL76030, a synchronous 4-switch buck-boost DC/DC controller in a 28-lead 4 mm x 5 mm QFN package. The proprietary peak-buck, peak-boost current-mode control scheme allows adjustable and synchronizable 600 kHz to 1.4 MHz fixed frequency operation, or internal 25% triangle spread-spectrum frequency modulation for low EMI. The board accepts a continuous 4 V to 25 V input voltage with transient voltage up to 55 V. Various test points are available for monitoring (PGOOD and ISMON) and control (EN/UVLO, CTRL, and SYNC). Optional EMI input, output, and gate resistor component placeholders are included to support the option of adding, if required.

Features

  • 4-Switch Single Inductor Architecture Allows VIN Above, Below, or Equal to VOUT
  • Up to 95% Efficiency at 1.4 MHz
  • Proprietary Peak-Buck, Peak-Boost Current-Mode
  • Wide VIN Range: 4 V to 55 V
  • ±2% Output Voltage Accuracy: 1 V ≤ VOUT ≤ 55 V
  • ±3% Input or Output Current Accuracy with Monitor
  • Spread-Spectrum Frequency Modulation for Low EMI
  • No Top MOSFET Refresh Noise in Buck or Boost
  • Adjustable and Synchronizable: 600 kHz to 1.4 MHz

Typical applications

  • Industrial Systems
  • High Frequency, Battery-Powered System
  • Telecom Systems
