Convenient Power CPSQ5453 | Demoboard CPSQ5453 EVALUATION BOARD

Dual-Channel Constant-Voltage and Constant-Current Controller with SPI Interface

Overview

TopologyBoost Converter
Input voltage4.5-65 V
Switching frequency100-700 kHz
IC revision1.0.1

Description

The CPSQ5453 is a dual full-independent channel constant-voltage and constant-current controller. CPSQ5453 operates over a wide input voltage range from 4.5V to 65V with SPI interface.The CPSQ5453 applies Peak-Current (PCM)control mode which provides fast load transient response and easy loop design and requires a minimal number of readily available, standard, external components. The frequency is programmable from 100kHz to 700kHz.
