HM3412

6V 6.0A 1.2MHz Synchronous Step-Down Regulator

GENERAL DESCRIPTION

FEATURES

The HM3412 is

high-efficiency, DC-to-DC



Low R_DS(ON)for internal switches(top/bottom):

35/15mΩ

step-down switching regulators, capable of delivering

up to 6A of output current. The HM3412 operates from

an input voltage range of 2.75V to 6.0V. It integrates

main switch and synchronous switch with very low

R_DS(ON). This low noise output along with its excellent

efficiency achieved by the internal synchronous

rectifier, making HM3412 an ideal green replacement

for large power consuming linear regulators.



2.75-6.0V input voltage range

High Efficiency: Up to 95%

6A continuous output current capability

Automatic PSM/PWM mode switch

1.2MHz Switching Frequency

Shutdown current <1μA

Low dropout 100% Duty operation

Internal Compensation and Soft-Start

Power good indicator

It is equipped with an automatic PSM/PWM mode

operation. At light load, the IC operates in the PSM

mode to reduce the switching losses. At heavy load,

the IC works in PWM mode.

OCP/UVLO/OTP protections

Available in DFN2x2-8 package

APPLICATIONS

Internal soft-start control circuitry reduces inrush

current. Short-circuit and thermal-overload protection

improves design reliability.



High definition Set Top Box

LCD TV

Notebook PC

The HM3412 is available in DFN2x2-8 Package.
