GPM9081

1.2 MHz Step-up DC/DC Converters

General Description

Features

The GPM9081 step-up switching regulator

generates an output voltage of up to 6V

from an input voltage as low as 1.6V. Ideal

for applications where space is limited, it

switches at 1.2MHz, allowing the use of

tiny, low cost and low profile external

components. Its internal 2A, 100mΩꢀ

NMOS switch provides high efficiency even

at heavy load, while the constant frequency,

current mode architecture results in low,

predictable output noise that is easy to

filter. Internal frequency compensation is

designed to accommodate ceramic output

capacitors, further reducing noise. The

device features very low shutdown current

of 0.5uA.

• Internal 2A MOSFET Switch

• 1.2MHZ Switching Frequency

• Integrated Soft-Start

• Low 1.6V Vin Operation

• Low R_ds(on)Switch :100mΩ at 5V Output

• Delivers 5V at 800mA from a 3.3V input

• Delivers 3V at 800mA from a 2.5V input

• Cost effective for using smaller devices

• Low profile(1mm):SOT-23-6 package

Application

• White LED Driver Supply

• Local 3.3V or 5V supply

• Battery Back-up

The GPM9081 is available in SOT-23-6

package.
