| THV1023-Rev0.06W Preliminary THV1023 2ch Buck Controller General Description THine's new 2ch Buck controller enables simple & low cost multi-channel power supply system design. Both of the Ch-1 and Ch-2 have standard PWM controller function and are designed to make phase compensation Features *TSSOP 16Pin package *Input Voltage range : 4.2 to 24.0V *Push Pull output for direct Power Mos driving *Optimized for Ceramic output capacitor *Complete PWM mode controller *Adjustable switching frequency 200kH to 1MHz 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 P_GOOD2 the ensured sequence control can be easily set and linked to the external circuit. This IC is suitable for power supply system for TV/monitor set, and general equipment. by external resister *Timer Latch Protection *SystemUVLO Function *Adjustable Soft Start time by external capacitor *Adjustable Timer Latch Delay time by external capacitor *Ch-1 and Ch-2 are fixed Buck controller in a ry Pin Assignment Applications *TFT LCD Bias power supply *TV/monitor set *General equipment lim TSSOP 16P 1 2 3 4 5 6 7 8 VREF SGND SS_1 INV_1 FB_1 VCC SYSUVLO OUT_1 RT 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. |
