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 turned on fully.
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 feedforward input-voltage compensation that responds instantly to input voltage change.
The integral 700-mV reference is trimmed to 2%, providing the means to accurately control low voltages.
The TPS40200-Q1 is available in an 8-pin SOIC package and supports many of the features of more complex controllers.
Clock frequency, soft start, and overcurrent limit are each easily programmed by a single, external component.
The device has undervoltage lockout (UVLO) and can be easily synchronized to other controllers or a system...
