3 Description

The TPS40200 is afexiblenon-synchronous
controller with a built-in 200-mA driver for P-channel
FETs. The circuit operates with inputs up to 52Vwith
a powersaving feature that turns offdriver current
once the external FET has been fully tuned on.This
feature extends the flexibility of the deviceallowing it
to operate with an input voltage up to 52 V without
dissipating excessive power.The circuit operates with
voltage-mode feedback and has feed-forward input
voltage compensation that responds instantly to input
voltage change. The integral 700-mVreference is
trimmed to 2%,providing the means to accurately
control low voltages. The TPS40200 is available in an
8-pin soic and an 8-pin ysoN package and
supports many of the features of more complex
controllers. Clockfrequency.soft-startand
overcurrent limits are each easily
