THV3056 - 3ch Buck/Boost 2ch CP 1ch HVLDO 1ch LVLDO Controller

Datasheet Summary

Description

THV3056 is a 3ch Buck/Boost Controller IC which enables to design simple & low cost multi-channel power supply system.

Ch-1(fixed Boost), ch-2 and ch-3(fixed Buck) are PWM controllers.

As to ch-2, the output of 1.2V is available because the reference voltage of ch-2 is 0.85V.

THV3056_Rev.2.00_E THV3056 3ch Buck/Boost 2ch CP 1ch HVLDO 1ch LVLDO Controller Description THV3056 is a 3ch Buck/Boost Controller IC which enables to design simple & low cost multi-channel power supply system. Ch-1(fixed Boost), ch-2 and ch-3(fixed Buck) are PWM controllers. As to ch-2, the output of 1.2V is available because the reference voltage of ch-2 is 0.85V. VGH and VGL are selectable Positive/Negative charge pumps and PFM controller. Built-in high voltage LDO and Vcom buffer amplifier facilitate to design various power supply systems for large scale TFT panels. THV3056 achieves easy phase compensation even with a ceramic capacitor for the output. SS_1/2/3, SS_SW, DTC1/2/3, DTC_VGH/DTC_VGL and SCP help to design user defined soft start time, dead time and timer latch delay time.
