Convenient Power CPSQ5453 | Demoboard CPSQ5453 EVALUATION BOARD

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.
