3 Description

The LMG5200 device, an 80-V, 10-A driver plus GaN

half-bridge power stage, provides an integrated

power stage solution using enhancement-mode

Gallium Nitride (GaN) FETs. The device consists of

two 80-V GaN FETs driven by one high-frequency

GaN FET driver in a half-bridge configuration.

GaN FETs provide significant advantages for power

conversion as they have near zero reverse recovery

and very small input capacitance CISS. All the devices

are mounted on a completely bond-wire free package

platform with minimized package parasitic elements.

The LMG5200 device is available in a 6 mm × 8 mm

× 2 mm lead-free package and can be easily

mounted on PCBs.

The TTL logic compatible inputs can withstand input

voltages up to 12 V regardless of the VCC voltage.

The proprietary bootstrap voltage clamping technique

ensures the gate voltages of the enhancement mode

GaN FETs are within a safe operating range.

The device extends advantages of discrete GaN

FETs by offering a more user-friendly interface. It is

an ideal solution for applications requiring highfrequency,

high-efficiency operation in a small form

factor. When used with the TPS53632G controller,

the LMG5200 enables direct conversion from 48-V to

point-of-load voltages (0.5-1.5 V).
