TPS53124

SLUS825C –FEBRUARY 2008–REVISED AUGUST 2014
TPS53124 Dual Synchronous Step-Down Controller
For Low-Voltage Power Rails Features 3 Description

The TPS53124isa dual, Adaptive on-time DCAP™ High Efficiency, Low-Power Consumption mode synchronous controller. The part enables• D-Cap Mode Enables Fast Transient Response system designers to cost effectively complete the• High Initial Reference Accuracy suiteof digital TV power bus regulators with the
absolute lowest external component count and lowest• Low Output Ripple standby consumption. The main control loop for the• Wide Input Voltage Range: 4.5Vto 24V TPS53124 uses the D-CAP™ mode that optimized• Output Voltage Range: 0.76Vto 5.5V for low ESR output capacitors such as POSCAPor
SP-CAP promises fast transient response with no• Low-Side RDS(on) Loss-less Current Sensing
external compensation. The part provides a• Adaptive Gate Drivers with Integrated Boost Diode convenient and efficient operation with conversion• Internal 1.2-ms Voltage-Servo Soft Start voltages from 4.5Vto 24V and output voltage from Built-In 5-V Linear Regulator 0.76Vto 5.5V.
The TPS53124 is available in the 24-pin RGE2 Applications package and in the 28-pin PW package and is Digital TV Power Supply specified from -40°Cto 85°C ambient temperature
range.• Networking Home Terminal Digital STB Device Information(1)
