The TPS53126 is a dual, adaptive on-time, D-CAP2™ mode synchronous Buck controller. The TPS53126 enables system designers to complete the suite of various end equipment’s power bus regulators with a cost effective, low external component count, and low standby current solution. The main control loop for the TPS53126 uses the D-CAP2™ mode control which provides a very fast transient response with no external components. The TPS53126 also has a proprietary circuit that enables the device to adapt to both low equivalent series resistance (ESR) output capacitors, such as POSCAP or SP-CAP, and ultra-low ESR ceramic capacitors. The device provides convenient and efficient operation with input voltages from 4.5 V to 24 V and output voltages from 0.76 V to 5.5 V.

The TPS53126 is available in 4mm × 4mm 24 pin VQFN (RGE) or 24 pin TSSOP (PW) packages and is specified from –40°C to 85°C ambient temperature range.
