• Programmable UVLO and Hysteresis Thermal Shutdownat 150°C DESCRIPTION• Selectable Soft-Start The TPS40195 isa flexible synchronous buck
• Pre-Bias Output Safe controller that operates froma nominal 4.5Vto 20V
supply. This controller implements voltage mode
control with the switching frequency adjustable from
APPLICATIONS100 kHzto 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
undervoltage lockout (UVLO) and synchronization
• Networking Equipmentcapability. An adaptive anti-cross conduction scheme
• Non-Isolated DC-DC modules is usedto prevent shoot through currentin the power
FETs. Over-current detectionis done by sensing the
voltage drop across the low-side MOSFET whenitis
on, and comparingit witha user programmable
threshold.
