The TPS54495 is a dual, adaptive on-time D-CAP2™ mode synchronous buck converter. The TPS54495 enables system designers to complete the suite of various end equipment’s power bus regulators with a cost effective, low component count, and low standby current solution. The main control loops of the TPS54495 use the D-CAP2™ mode control which provides a very fast transient response with no external compensation components. The adaptive on-time control supports seamless transition between PWM mode at higher load conditions and Eco-mode™ operation at light loads. Eco-mode™ allows the TPS54495 to maintain high efficiency during lighter load conditions. The TPS54495 is able 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 4.5V to 18V.

The TPS54495 is available in a 4.4 mm × 5 mm 16-pin TSSOP (PWP) package and 4 mm x 4 mm 16-pin VQFN (RSA), and is designed to operate for an ambient temperature range from –40°C to 85°C.

This solution stores and delivers "last gasp" energy for systems, such as SSDs, that require functionality for a short time after power loss in order to shut down in a controlled fashion. By storing holdup energy at higher than bus voltage the amount of capacitance can be reduced by up to 80%, (...)
