TPS40200
SLUS659G – FEBRUARY 2006 – REVISED NOVEMBER 2014
TPS40200 Wide Input Range Non-Synchronous Voltage Mode Controller
1 Features
3 Description
The
TPS40200
is
a
flexible,
non-synchronous

Input Voltage Range 4.5 V to 52 V
controller with a built-in 200-mA driver for P-channel
Output Voltage (700 mV to 90% VIN)
FETs. The circuit operates with inputs up to 52 V with
200-mA Internal P-channel FET Driver
a power-saving feature that turns off driver current
once the external FET has been fully turned on. This
Voltage Feed-Forward Compensation
feature extends the flexibility of the device, allowing it
Undervoltage Lockout
to operate with an input voltage up to 52 V without
Programmable Fixed-Frequency (between 35 kHz
dissipating excessive power. The circuit operates with
and 500 kHz) Operation
voltage-mode feedback and has feed-forward input
voltage compensation that responds instantly to input
Programmable Short-Circuit Protection
voltage change. The integral 700-mV reference is
Hiccup Overcurrent Fault Recovery
trimmed to 2%, providing the means to accurately
Programmable Closed-Loop Soft-Start
control low voltages. The TPS40200 is available in an
700 mV 1% Reference Voltage
8-pin SOIC and an 8-pin VSON package and
supports many of the features of more complex
External Synchronization
controllers.
