TPS40195PWR Datasheet

DC/DC Switching Controllers


The TPS40195PWR is a flexible synchronous buck controller that operates from a nominal 4.5 V to 20 V supply. This controller implements voltage mode control with the switching frequency adjustable from 100 kHz to 600 kHz. Flexible features found on this device include selectable soft-start time,programmable short circuit limit, programmable undervoltage lockout (UVLO) and synchronization capability. An adaptive anti-cross conduction scheme 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. TPS40195PWR Features • Input Operating Voltage Range: 4.5 V to 20 V• Output Voltage as Low as 0.591 V ±0.5%• 180° Bi-Directional Out-of-Phase Synchronization• Internal 5-V Regulator• High and Low MOSFET Sense Overcurrent• 100 kHz to 600 kHz Switching Frequency• Enable and Power Good• Programmable UVLO and Hysteresis• Thermal Shutdown at 150°C• Selectable Soft-Start• Pre-Bias Output Safe
