The TPS566235 is a cost effective, high-voltage input, high efficiency synchronous Buck converter with integrated FETs. It enables system designers to complete the suite of various end-equipment power bus regulators with a cost effective, low component count, low standby current solution.

The TPS566235 employs the D-CAP3™ mode control that provides a fast transient response and good line/load regulation with no external compensation components. It also has a proprietary circuit that enables the device to support low equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors. The control topology supports seamless transition between CCM mode at heavy load conditions and DCM operation at light load conditions. There are three operation modes can be configured by MODE pin at light load: Eco-Mode™, Out-Of-Audio™ (OOA) and Forced Continuous Conduction Mode (FCCM). The OOA mode is a unique control feature that keeps the switching frequency above audible frequency with minimum reduction in efficiency.

The TPS566235 supports pre-biased start up and power good indicator. It provides complete protection including OVP, UVP, OCP, OTP and UVLO. The device is available in 3.0-mm x 2.0-mm HotRod™ package and the junction temperature is specified from –40°C to 125°C.
