| THV1022-Rev0.05W 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 20.0V *Push Pull output for direct Power Mos driving *Optimized for Ceramic output capacitor *Complete PWM mode controller *Adjustable switching frequency 200kH to 800KHz by external resister *Timer Latch Protection *UVLO Function *Adjustable Soft Start time by external capacitor *Adjustable Timer Latch Delay time by external capacitor *Ch-1 is fixed Boost controller *Ch-2 is fixed Buck controller in a ry Pin Assignment Applications * TFT LCD Bias voltage supply * General equipment lim TSSOP 16P 1 2 3 4 5 6 7 8 RT SGND SS_1 INV_1 FB_1 VCC XP_GOOD1 OUT_1 VREF SCP SS_2 INV_2 FB_2 OUT_2 P_GOOD2 PGND 16 15 14 13 12 11 10 9 P re THine Electronics, Inc. |
