THV3011_Rev.1.00_E
THV3011
1ch DC/DC converter
Description
THV3011 is a synchronous buck switching regulator
IC with the external High side Power MOSFET.
Available high current power supply using a mini-
mum number of external components, because any
external phase compensation parts are not necessary.
The bootstrap technology provides high efficiency
more than 97%. Utilizing the latest and THine’s
unique architecture, THV3011 achieves ultra quick
transient response.
Soft start by SS pins makes constant and stable soft
start curve not depend on the load fluctuation.
THV3011 also has the Power-good function and the
Off-delay function to facilitate the setting of On/Off
sequence.
