Description

TS19701A is a high performance offline PWM Power switch for low power AC/DC charger and adapter

applications. It operates in primary-side sensing and regulation. Consequently, opto-coupler and TS431 could be

eliminated. Proprietary Constant Voltage (CV) and Constant Current (CC) control is 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.

TS19701A offers power on soft start control and protection coverage with auto-recovery features including Cycle-

by- Cycle current limiting, VDD OVP, VDD clamp and UVLO. Excellent EMI performance is achieved with Power-

Source proprietary frequency shuffling technique. High precision constant voltage (CV) and constant current (CC)

can be achieved by TS19701A
