LM27313

1.6 MHz Boost Converter With 30V Internal FET Switch in

SOT-23

General Description

The LM27313 switching regulator is a current-mode boost

converter with a fixed operating frequency of 1.6 MHz.

The use of the SOT-23 package, made possible by the mini-

mal losses of the 800 mA switch, and small inductors and

capacitors result in extremely high power density. The 30V

internal switch makes these solutions perfect for boosting to

voltages of 5V to 28V.

Features

30V DMOS FET switch

■

1.6 MHz switching frequency

Low R_DS(ON) DMOS FET

Switch current up to 800 mA

Wide input voltage range (2.7V–14V)

Low shutdown current (<1 µA)

5-Lead SOT-23 package

This part has a logic-level shutdown pin that can be used to

reduce quiescent current and extend battery life.

Uses tiny capacitors and inductors

Protection is provided through cycle-by-cycle current limiting

and thermal shutdown. Internal compensation simplifies de-

sign and reduces component count.
