Preliminary
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 pensation 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.
