Conv DC-DC Single Step Down 2V to 18V 16-Pin PQFN T/R
The TPS53511 is an adaptive on-time D-CAP2 mode synchronous buck converter.The device is suitable for points-of-load (POL) in computing power systems, andprovides a cost-effective, low component count, low standby current solution.The main control loop for the TPS53511 uses the D-CAP2 mode control providing afast transient response with no external components. The adaptive on-timecontrol supports seamless operation between PWM mode during heavy loadconditions and reduced frequency operation during light load conditions for highefficiency.
The TPS53511 includes a proprietary circuit that enables the device to adaptto both low equivalent series resistance (ESR) output capacitors, such as POSCAPor SP-CAP, and ultra-low ESR ceramic capacitors. The device operates from 4.5-Vto 18-V supply input, and from 2-V to 18-V input power supply voltage. Thedevice features an adjustable slow start time and a power good function. It alsosupports pre-biased soft start. The TPS53511 is available in the 16-pin QFN
