LM2725/LM2726 High Speed Synchronous MOSFET Drivers

Check for Samples: LM2725, LM2726

FEATURES

DESCRIPTION

The LM2725/LM2726 is a family of dual MOSFET

drivers that drive both the top MOSFET and bottom

MOSFET in a push-pull structure simultaneously. It

takes a logic level PWM input and splits it into two

complimentary signals with a typical 20ns dead time

in between. The built-in shoot-through protection

circuitry prevents the top and bottom FETs from

turning on simultaneously. With a bias voltage of 5V,

the peak sourcing and sinking current for each driver

of the LM2725 is about 1.2A and that of the LM2726

is about 3A. In an SOIC-8 package, each driver is

able to handle 50mA average current. When EN

signal is asserted the input UVLO (Under Voltage

Lock Out) ensures that all the driver outputs stay low

until the supply rail exceeds the power-on threshold

during system power on, or after the supply rail drops

below power-on threshold by a specified hysteresis

during system power down. The cross-conduction

protection circuitry detects both the driver outputs and

will not turn on a driver until the other driver output is

low. The top gate bias voltage needed by the top

MOSFET can be obtained through an external

bootstrap structure. Minimum input pulse width is as

low as 55ns.

Typical Application

Note: for ultra low-frequency operation (such as

skip mode at light load), D₁should be a fast

recovery type diode instead of a Schottky.
