RT5758 - 1MHz Synchronous Step-Down Converter

Description

The RT5758 is a high-performance, synchronous stepdown DC-DC converter that can deliver up to 9A output current from a 3V 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.

Features

  • are also integrated in the device including the cycle-by-cycle current limit control, UVP, input UVLO and OTP. The RT5758 is available in a thermally enhanced UQFN13L 3x3 (FC) package. Ordering Information RT5758 Package Type QUF : UQFN-13L 3x3 (FC) (U-Type) Lead Plating System G : Green (Halogen Free and Pb Free) Note : Richtek products are :  RoHS compliant and compatible with the current requirements of IPC/JEDEC J-STD-020.  Suitable for use in SnPb or Pb-free soldering processes.

® RT5758 9A, 6.5V, 1MHz Synchronous Step-Down Converter General Description The RT5758 is a high-performance, synchronous stepdown DC-DC converter that can deliver up to 9A output current from a 3V 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 RT5758 adopts Advanced Constant On-Time (ACOTTM) control architecture that provides ultrafast transient response and further reduce the external-component count. In steady states, the ACOTTM operates in nearly constant switching frequency over line, load and output voltage ranges and makes the EMI filter design easier.
