FEATURES
DESCRIPTION
The LM27313 switching regulator is a current-mode
2
LM27313-Q1 is an Automotive Grade Product
boost converter with a fixed operating frequency of
that is AEC-Q100 Grade 1 Qualified (-40°C to
1.6 MHz.
+125°C Operating Junction Temperature)
The use of the SOT-23 package, made possible by
30V DMOS FET Switch
the minimal losses of the 800 mA switch, and small
1.6 MHz Switching Frequency
inductors and capacitors result in extremely high
Low RDS(ON) DMOS FET
power density. The 30V internal switch makes these
solutions perfect for boosting to voltages of 5V to
Switch Current up to 800 mA
28V.
Wide Input Voltage Range (2.7V–14V)
This part has a logic-level shutdown pin that can be
Low Shutdown Current (<1 µA)
used to reduce quiescent current and extend battery
5-Lead SOT-23 Package
life.
Uses Tiny Capacitors and Inductors
Protection is provided through cycle-by-cycle current
Cycle-by-Cycle Current Limiting
limiting and thermal shutdown. Internal compensation
Internally Compensated
simplifies design and reduces component count.
APPLICATIONS
White LED Current Source
PDA’s and Palm-Top Computers
Digital Cameras
Portable Phones, Games and Media Players
GPS Devices
