Texas Instruments  TPS54626PWPR

The TPS54626 is an adaptive on-time D-CAP2™ mode synchronous Buck converter. The TPS54626 enables system designers to complete the suite of various end equipment’s power bus regulators with a cost effective, low component count, low standby current solution. The main control loop for the TPS54626 uses the D-CAP2™ mode control which provides a very fast transient response with no external components. The adoptive on-time control supports seamless operation between PWM mode at heavy load condition and reduced frequency operation at light load for high efficiency. The TPS54626 also has a proprietary circuit that enables the device to adopt to both low equivalent series resistance (ESR) output capacitors, such as SP-CAP and ultra-low ESR ceramic capacitors. The device operates from 4.5-V to 18-V VIN input power supply voltage. The output voltage can be programmed between 0.76 V and 5.5 V. The device also features an adjustable soft start time and a power good function. The TPS54626 is available in the 14 pin HTSSOP package, designed to operate from –40°C to 85&#deg;C.
