The TPS40195 is a flexible synchronous buck • Pre-Bias Output Safe controller that operates from a nominal 4.5 V to 20 V supply. This controller implements voltage mode APPLICATIONS control with the switching frequency adjustable from 100 kHz to 600 kHz. Flexible features found on this • Digital TV device include selectable soft-start time, • Entry-Level and Midrange Servers programmable short circuit limit, programmable • Networking Equipment undervoltage lockout (UVLO) and synchronization capability. An adaptive anti-cross conduction scheme • Non-Isolated DC-DC modules is used to prevent shoot through current in the power FETs. Over-current detection is done by sensing the voltage drop across the low-side MOSFET when it is on, and comparing it with a user programmable threshold.
