TPS50601-DIE (ACTIVE)

1.6-V to 6.3-V Input, 6-A Synchronous Step Down Converter, TPS50601-DIE

 

Description

The TPS50601-DIE is a 6.3-V, 6-A synchronous step-down converter which is optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs. Further space savings are achieved through current mode control, which reduces component count, and a high switching frequency, reducing the inductor’s footprint.

The output voltage startup ramp is controlled by the SS/TR pin which allows operation as either a standalone power supply or in tracking situations. Power sequencing is also possible by correctly configuring the enable and the open-drain power good pins.

Cycle-by-cycle current limiting on the high-side FET protects the device in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. A low-side sinking current limit also turns off the low-side MOSFET to prevent excessive reverse current. Thermal shutdown disables the part when die temperature exceeds thermal shutdown temperature.
