CX8503 8~40V Input CC and CV Step-Down DC/DC Converter
GENERAL DESCRIPTION
CX8503 is a wide input voltage, high efficiency CC and CV step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. CX8503 provides low-ripple power, high efficiency, and excellent transient characteristics. The PWM control circuit is able to the duty ratio linearly forms 0 up to 90%. An over current protection and short circuit protection functions are built outside that it can set by a resistance. An external compensation is easily to system stable; the low ESR output capacitor can be used.
