LM27313/LM27313-Q1

Check for Samples: LM27313

FEATURES

DESCRIPTION

The LM27313 switching regulator is a current-mode

boost converter with a fixed operating frequency of

1.6 MHz.

•

LM27313-Q1 is an Automotive Grade Product

that is AEC-Q100 Grade 1 Qualified (-40°C to

+125°C Operating Junction Temperature)

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

the minimal 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.

•

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

Cycle-by-Cycle Current Limiting

Internally Compensated

Protection is provided through cycle-by-cycle current

limiting and thermal shutdown. Internal compensation

simplifies design and reduces component count.
