       CXSD62343 CXSD62344 is a wide input voltage, high efficiency step-down DC/DC converter which operates in either CV (Constant Voltage) mode or CC (Constant Current) mode. This device includes a reference voltage source, oscillation circuit, error amplifier, integrated high-side power mos, a pwm controller and a constant current controller. CXSD62343 CXSD62344 provides up to 4.0A output current at 125 KHz switching frequency. CC eliminates the expensive, high accuracy current sense resistor, making it ideal for battery charging applications and adaptors with accurate current limit. CXSD62343 CXSD62344achieves higher efficiency than traditional constant current switching regulators by eliminating its associated power loss. Standard protection features include cycle by cycle current limit, thermal shutdown, and frequency fold-back at short circuit. The devices are available in a SOP-8EP package and require few external devices for operation.
