MP2491C

32V, 6A, Step-Down Converter

with Programmable Current Limit

and Output Voltage Scaling Control

DESCRIPTION

FEATURES

The MP2491C is a fully integrated, high-voltage,

step-down converter. The MP2491C can

achieve 6A of continuous output current with

excellent load and line regulation over a wide

input supply range.



Wide 4.0V to 32V Operating Input Range

0.5V to 30V Output Voltage Range

6A Output Current

Constant-on-Time (COT) Control

Two Dedicate Voltage Scaling Control Pins

Slew Rate Control during DVS

Low Dropout Mode Operation

33mΩ/22mΩ Internal MOSFET Switches

450µA I_Q

Fixed 490kHz Switching Frequency

Output Line Drop Compensation when V_FB

0.5V

EN Shutdown Discharge

Output Over-Voltage Protection (OVP)

Adjustable Auto-PFM/PWM Mode or Forced

PWM Mode

Adjustable Current Limit

Power Good (PG) Indication

Available in a QFN-13 (2.5mmx3mm)

Package

Constant-on-time (COT) control operation

provides very fast transient response, easy loop

design, and very tight output regulation.

Full protection features include over-current

protection (OCP), hiccup current limiting, output

over-voltage protection (OVP), and thermal

shutdown.



The MP2491C requires a minimal number of

readily

available,

standard,

external

components and is available in a QFN-13

(2.5mmx3mm) package.



APPLICATIONS



TVs, Monitors

MFP Power Supplies

USB Power Supplies with PD

Automotive Cigarette Lighter Adapters
