THV1022-Rev0.05W www.DataSheet4U.com Preliminary THV1022 2ch Buck/Boost Controller General Description THine's new 2ch Buck and Boost controller enables simple & low cost multi-channel power supply system design. Ch-1 is Boost controller, ch-2 is Buck controller. Both channels are PWM controllers and are designed to make phase compensation easy for output ceramic capacitors. SS_1,2 and SCP pins help to design user defined soft start time, and timer latch delay time. Utilizing those pins and XP_GOOD1,P_GOOD2 the ensured sequence control can be easily set and linked to the external circuit. This IC is suitable for power supply system of TFT LCD bias. Features •TSSOP 16Pin package •Input Voltage range : 4.2 to 20.
