General Description

The RTQ2158B is a high-performance, Advanced Constant On-Time (ACOT® ) monolithic synchronous step-down DC-DC converter that can deliver up to 8A output current from a 2.85V to 6.5V input supply.

The device integrates low RDS(ON) power MOSFETs, accurate 0.6V reference and an integrated diode of bootstrap circuit to offer a very compact solution.

The RTQ2158B adopts Advanced Constant On-Time (ACOT® ) control architecture that provides ultrafast transient response and further reduces the external-component count.

Key Features

  • are also integrated in the device including the cycle-by-cycle current limit control, UVP, input UVLO and OTP. The RTQ2158B-QA is available in a thermally enhanced WET-WQFN-21L 4x4 (FC) package. Features.
  • AEC-Q100 Grade 1 Qualified.
  • Dramatically Fast Transient Response.
  • Steady 460kHz Switching Frequency.
  • Extremely High Efficiency 15m/10m MOSFETs.
  • Advanced COT Control Loop.
  • Wide Input Voltage Range from 2.85V to 6.5V.
  • Optimized for Ceramic Output Capacitors.
