RTQ2158-QA

8A, 6.5V, 2.1MHz Synchronous Step-Down Converter

Features

 AEC-Q100 Grade 1 Qualified

General Description

The RTQ2158 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 R_DS(ON)power MOSFETs,

accurate 0.6V reference and an integrated diode of

bootstrap circuit to offer a very compact solution.

 Dramatically Fast Transient Response

 Steady 2.1MHz 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

 Internal Start-Up into Pre-biased Outputs

 Power Good Indicator

The RTQ2158 adopts Advanced Constant On-Time

(ACOT^®) control architecture that provides ultrafast

transient response and further reduces the

external-component count. In steady states, the

ACOT^®operates in nearly constant switching

frequency over line, load and output voltage ranges

and makes the EMI filter design easier.

 Enable Control

 Over-Current and Over-Temperature Protections

 Under-Voltage Protection with Hiccup Mode

Applications

 Automotive Systems

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 RTQ2158-QA is available in

a thermally enhanced WET-WQFN-21L 4x4 (FC)

package.
