FEATURES  
DESCRIPTION

High Efficiency, Low-Power Consumption,  
Shutdowns to <1 mA  
The TPS59124 is a dual, adaptive on-time D-CAP™  
mode synchronous buck controller. This device  
enables system designers to cost effectively complete  
the suite of embedded computer power bus  
regulators with the absolute lowest external  
component count and lowest standby consumption.  
The fixed-frequency emulated adaptive on-time  
control supports seamless operation between PWM  
mode at heavy load condition and reduced frequency  
operation at light load for high-efficiency down to  
milliampere range. The main control loop for the  
TPS59124 uses the D-CAP mode that optimized for  
low-ESR output capacitors such as POSCAP or  
SP-CAP promises fast transient response with no  
external compensation. Simple and separate power  
good signals for each channel allow flexibility of  
power sequencing. The device provides convenient  
and efficient operation with supply input voltages  
(V5IN, V5FILT) ranging from 4.5 V to 5.5 V,  
conversion voltages (drain voltage for the  
synchronous high-side MOSFET) from 3 V to 28 V  
and output voltages from 0.76 V to 5.5 V.  
Fixed Frequency Emulated On-Time Control,  
Frequency Selectable From Three Options  
D-CAP™ Mode Enables Fast Transient  
Response  
Auto-Skip Mode  
Less Than 1% Initial Reference Accuracy  
Low Output Ripple  
Wide Input Voltage Range: 3 V to 28 V  
Output Voltage Range: 0.76 V to 5.5 V  
Low-Side RDS(on) Loss-less Current Sensing  
Adaptive Gate Drivers With Integrated Boost  
Diode  
Internal 1.2-ms Voltage-Servo Soft Start  
Power-Good Signals for Each Channel With  
Delay Timer  
Output Discharge During Disable, Fault  
APPLICATIONS  
The TPS59124 is available in 24-pin QFN package  
specified from –40°C to 85°C ambient temperature  
range.
