Preliminary Datasheet LP1130A
Half-Bridge IPM
General Description
The LP1130A is a high efficiency synchronous buck
power stage module consisting of two asymmetrical
MOSFETs and an integrated driver. The MOSFETs
are individually optimized for operation in the
synchronous buck configuration. The high side and
low side MOSFETs has ultra low R
DS(ON)
to minimize
conduction losses.
A number of features are provided making the
LP1130A a highly versatile power module.

Description
1
BST
Upper MOSFET Floating Bootstrap Supply. A capacitor connected between BST and
SW pins holds this bootstrap voltage for the high-side MOSFET as it is switched. The
recommended capacitor value is between 100nF and 1.0μF. An external diode is
required with the LP1130A.
2
PWM
Logic-Level Input. This pin has primary control of the drive outputs.
3
EN
Active high output enable. When low, normal operation is disabled.
4
VCC
Input Supply. A 1.0μF ceramic capacitor should be connected from this pin to PGND.
5,6
SWN
Switch Node. Connect to the source of the upper MOSFET.
7
PGND
Power Ground. Should be closely connected to the source of the lower MOSFET.
8
VIN
Source for the upper MOSFET
