WIDE INPUT RANGE NON-SYNCHRONOUS VOLTAGE MODE CONTROLLER
Input Voltage Range 4.5 to 52 V
Output Voltage (700 mV to 90% V
IN)
The
TPS40200
is
a
flexible
non-synchronous
controller with a built in 200-mA driver for P-channel
200 mA Internal P-Channel FET Driver
FETs. The circuit operates with inputs up to 52 V with
Voltage Feed-Forward Compensation
a power-saving feature that turns off driver current
Undervoltage Lockout
once the external FET has been fully turned on. This
feature extends the flexibility of the device, allowing it
Programmable Fixed Frequency (35–500 kHz)
to operate with an input voltage up to 52 V without
Operation
dissipating excessive power. The circuit operates with
Programmable Short Circuit Protection
voltage-mode
feedback
and
has
feed-forward
Hiccup Overcurrent Fault Recovery
input-voltage compensation that responds instantly to
input voltage change. The integral 700-mV reference
Programmable Closed Loop Soft Start
is trimmed to 2%, providing the means to accurately
700 mV 1% Reference Voltage
control low voltages. The TPS40200 is available in
External Synchronization
and 8-pin SOIC and an 8-pin QFN package and
supports many of the features of more complex
Small 8-Pin SOIC (D) and QFN (DRB) Packages
controllers.
Clock
frequency,
soft-start,
and
overcurrent limit are each easily programmed by a
single,
external
component.
The
part
has
Industrial Control
