Part Number: TPS40200HD ( Marking 40200S ), TPS40200-HT
Function: High Temperature Wide Input Non-Synchronous Buck DC/DC Controller
Package: SOIC 8 Pin Type
Manufacturer: Texas Instruments
The TPS40200HD is a flexible nonsynchronous controller with a built-in 200-mA driver for P-channel FETs. The circuit operates with inputs up to 52 V, with a power-saving feature that turns off driver current once the external FET has been fully turned on.
This feature extends the flexibility of the device, allowing 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.
