GENERAL DESCRIPTION
Consequently, opto-coupler and TL431 could be eliminated. High Precision Constant Voltage (CV) and Constant Current (CC) control are integrated as shown in the figure below. In CC control, the current and output power setting can be adjusted externally by the sense resistor Rs at CS pin. In CV control, multi-mode operations are utilized to achieve high performance and high efficiency. In addition, good load regulation is achieved by the built-in Cable Drop Compensation. Device operates in PFM in CC mode as well at large load condition and it operates in PWM with frequency reduction at light/medium load. The chip consumes very low operation current, it can achieve less than 80mW standby power. High precision constant voltage (CV) and constant current (CC) can be achieved by DP2532. DP2532 is offered in SOT23-6 package.. TYPICAL APPLICATIONFEATURES
