Product Details

Description

The LTC® 3245is a switched capacitor buck-boost DC/DC converter that produces a regulated output (3.3V, 5V or adjustable) from a 2.7V to 38V input. The device uses switched capacitor fractional conversion to maintain regulation over a wide range of input voltage. Internal circuitry automatically selects the conversion ratio to optimize efficiency as input voltage and load conditions vary. No inductors are required.

Features

2.7V to 38V VINRange
IQ= 18µA Operating; 4μA in Shutdown
12V to 5V Efficiency = 81%
Multimode Operation (2:1, 1:1, 1:2) with Automatic Mode Switching
Low Noise, Constant Frequency Operation
Pin Selectable Burst Mode® Operation
VOUT: Fixed 3.3V, 5V or Adjustable (2.5V to 5V)
IOUTUp to 250mA
Overtemperature and Short-Circuit Protection
Operating Junction Temperature: 150°C Maximum
Thermally Enhanced 12-Pin MSOP and Low Profile 12-Pin (3mm × 4mm) DFN Packages

ApplicaTions

Automotive ECU/CAN Transceiver Supplies
Industrial Housekeeping Supplies
Low Power 12V to 5V Conversion
