The TPS65283-1RGER is a synchronous dual Buck Converter with power distribution switch. It is which is optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs. The device also incorporates one N-channel MOSFET power switches for power distribution systems. This device provides a total power distribution solution, where precision current limiting and fast protection response are required. The 60mR independent power distribution switch limits the output current to a programmable current limit threshold between typical 100mA to about 2.7A by using an external resistor. The current limit accuracy can be achieved as tight as ±10% at typical 1.25A. The nFAULT output asserts low under overcurrent and reverse-voltage conditions. Constant frequency peak current mode control in DC-DC converter simplifies the compensation and optimizes transient response.
