THV1021-Rev0.05W www.DataSheet4U.com Preliminary THV1021 2ch Buck, Boost and Inverting Controller General Description THine's new 2ch Buck/Boost & Inverting controller enables simple & low cost multi-channel power supply system design. Ch-1 is selectable Buck/Boost controller, ch-2 is selectable Inverting / Buck converter. All channels are PWM controllers and are designed to make phase compensation easy for output ceramic capacitors. SS_1,2, DTC_1,2, and SCP pins help to design user defined soft start time, dead time and timer latch delay time. Utilizing those pins and P_GOOD 1,2, 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 and for system board with multi-channel power supply.
