EUP3412

1.5A/1.5MHz, Synchronous

Step-Down Converter with Soft Start

DESCRIPTION

FEATURES

The EUP3412 is

a synchronous current mode

High Efficiency up to 96%

1.5A Available Load Current

step-down dc-dc converter, capable of driving 1.5A load

current with excellent line and load regulation.

Operating with an input voltage range between 2.7V

and 5.5V, the device is ideal for portable applications

NiMH/NiCd batteries. The EUP3412 operates at a fixed

switching frequency of 1.5MHz and PWM operation

provides very low output ripple voltage for noise

sensitive applications. The internal integrated

synchronous switch increases efficiency while

eliminates the need for an external Schottky diode. The

EUP3412 is available in the 10-pin MSOP and 10-pin

TDFN package.

300µA Typical Quiescent Current

1.5MHz Constant Switching Frequency

2.7V to 5.5V Input Voltage Range

Adjustable Output Voltage as Low as 0.7V

100% Duty Cycle Low Dropout Operation

No Schottky Diode Required

Short Circuit and Thermal Protection

Excellent Line and Load Transient Response

＜1µA Shutdown Current

Soft Start Function

Available in MSOP-10 and TDFN-10 Package

RoHS Compliant and 100% Lead(Pb)-Free

APPLICATIONS

Cellular and Smart Phones

Portable Media Players/ MP3 Players

Digital Still and Video Cameras

Portable Instruments

WLAN PC Cards
