Description

The TPS54395 is a dual, adaptive on-time D-CAP2™ mode synchronous buck converter. The TPS54395 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 TPS54395 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 TPS54395 to maintain high efficiency during lighter load conditions. The TPS54395 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 TPS54395 is available in a 4.4 mm × 5 mm 16-pin TSSOP (PWP) and 4 mm x 4 mm 16-pin VQFN (RSA) package, and is specified for an ambient temperature range from –40°C to 85°C.
