Pin Assignment
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
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.
