TPS
The TPS5120 TI 7CJ P23H is a highly sophisticated dual current mode synchronous step-down
Controller. It is a full featured controller designed to run directly off a three-or four-
Cell Li-ion battery and provide high-power and 5-v and/or 3.3-V standby regulation for
All the downstream circuitry in a notebook computers system.High current. 100-Ma,
5-V or 3.3-V on-board linear regulators have glitch-free switch over function to SMPS
And can be kept alive independently during standby state. The pseudo-constant
Frequency adaptive on – time control scheme supports full range of current mode
Operation including simplified loop compensation , ceramic output capacitors as well as
Seamless transition to reduced frequency operation at light-load condition.
