目录7.相关产品 产品概述 返回TOP CXSD62325 is a wide input voltage, high efficiency Active CC step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. CXSD62325 consists of step-down switching regulator with PWM control. The device includes a reference voltage source, oscillation circuit, error amplifier and etc. CXSD62325provides 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 function is 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. With the addition of an internal N-channel Power MOS, a coil, capacitors, and a diode connected externally, these ICs can function as step-down switching regulators. They serve as ideal power supply units for portable devices when coupled with the PSOP-8 packages, providing such outstanding features as low current consumption. Since this converter can accommodate an input voltage up to 36V产品特点 返回TOP Input Voltage:8V to 36V Vout Accuracy (VFB=1V) ±2% CC/CV mode(Constant Current and Constant Voltage) Up to 2.8A output current ±3%/±5%/15%Current limit Accuracy Duty ratio:0% to 90% PWM control Oscillation frequency:250KHz Thermal Shutdown function.
