The LM2700 is a step-up DC/DC converter with a 3.6A, 0.08Ω internal switch and pin selectable operating frequency. With the ability to produce 500mA at 8V from a single Lithium Ion battery, the LM2700 is an ideal part for biasing LCD displays. The LM2700 can be operated at switching frequencies of 600kHz and 1.25MHz allowing for easy filtering and low noise.
The LM2700 is a step‑up PWM DC/DC converter designed for biasing LCD displays and portable applications. It features a 3.6 A internal switch, selectable 600 kHz or 1.25 MHz switching frequencies, and can deliver up to 500 mA at 8 V from a single Li‑ion cell.

The LM2700 operates from 2.2 V to 12 V.
The output voltage is set using the feedback pin (1.26 V) and a resistor divider connected to the output.
The device can be configured for either 600 kHz or 1.25 MHz via the FSLCT pin.
It is offered in a 14‑lead TSSOP package or a 14‑lead LLP package.
