1.8V Input PWM Step-Up Regulator

The ISL98012 is a high frequency, high efficiency step-up

DC/DC regulator operated in fixed frequency PWM mode.

With an integrated 1.4A MOSFET, it can deliver up to 600mA

output current at up to 92% efficiency. The adjustable

switching frequency is up to 750kHz, making it ideal for

common boost applications.

When shut down, it draws <1µA of current. This feature,

along with the minimum starting voltage of 1.8V, makes it

suitable for portable equipment powered by 1 Lithium Ion,

3 to 4 NiMH cells, or 2 cells of alkaline battery.

The ISL98012 is available in a 10 Ld MSOP package, with a

maximum height of 1.1mm. With proper external

components, the whole converter takes less than 0.25in

PCB space.

This device is specified for operation over the full -40°C to

+85°C temperature range.
