A.4.3 Description
The TPS40200 is a flexible non-synchronous
controller with a built in 200-mA driver for P-channel
FETs. The circuit operates with inputs up to 52V with
a power-saving feature that turns off driver current
once the external FET has been fully turned on. This

Operation
feature extends the flexibility of the device, allowing
it to operate with an input voltage up to 52V without
dissipating excessive power. The circuit operates
with voltage-mode feedback and has feed-forward
input-voltage compensation that responds instantly
• 700 mV 1% Reference Voltage
• External Synchronization
• Small 8-Pin SOIC (D) and QFN (DRB) Packages
A.4.2 Applications

to input voltage change. The internal 700mV
reference is trimmed to 1%, providing the means to
accurately control low voltages. The TPS40200 is
available in an 8-pin SOIC, and supports many of the
features of more complex controllers.
