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.

The device offers Independent enable control input pin and

power good indicator for easily sequence control. To

control the inrush current during the startup, the device

provides a programmable soft-start up by an external

capacitor connected to the SS pin. Fully protection

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 UQFN-

13L 3x3 (FC) package.
