Description

General part information

LM27213 Series

The LM27213 is a single-phase synchronous buck regulator controller designed to fully support a portable microprocessor. On-chip gate drive makes for a compact, single chip solution. Output currents in excess of 25 Amps are possible.

The IC employs a current mode hysteretic control mechanism. Inductor current is sensed through a low value sense resistor.

The LM27213 will operate over an input voltage range of 5V to 30V. The output voltage is programmed through 6 Voltage Identification (VID) pins and ranges from 0.700V to 1.708V in 64 steps.
