TPS65286RHDR Datasheet PDF - TI

The TPS65286 is a full featured 4.5-V to 28-V VIN, 6-A output current synchronous step down DCDC converter, which is optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs. The device also incorporates dual 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.

●A dual 100-m&937; independent power distribution switch limits the output current to a programmable current limit threshold between typical 50 mA~2.7 A by using an external resistor. The current limit accuracy can be achieved as tightly as ±6% at typical 1.2 A. The nFAULT output asserts low under over-current and reverse-voltage conditions.

●Constant frequency peak current mode control in the DCDC converter simplifies the compensation and optimizes transient response. Cycle-by-cycle over-current protection and operating in hiccup mode limit MOSFET power dissipation. When die temperature exceeds thermal over loading threshold, the over temperature protection shuts down the device.
