TPS53015 - Synchronous Step-Buck Converter

General Description

The TPS53015 device is a single, adaptive on-time D-CAP2 ™ mode synchronous buck controller.

The device enables system designers to complete the suite of various end equipment power bus regulators with cost effective low external component count and low standby current solution.

Key Features

  • 1 D-CAP2™ mode control.
  • Fast transient response.
  • No external parts required for loop compensation.
  • Compatible with ceramic output capacitors.
  • High initial reference accuracy (±1%).
  • Wide input voltage 4.5 V to 28 V.
  • Output voltage 0.77 V to 7 V.
  • Low-side RDS(on) Loss-less current sensing.
  • Fixed soft-start time: 1.4 ms.
  • Non-sinking pre-biased soft start.
  • Switching frequency: 500 kHz.
  • Cycle-b.
