What are the key features of LM5035BMH/NOPB?
- Integrated half-bridge gate drivers with shoot-through protection simplify high-side and low-side MOSFET drive in isolated DC-DC designs
- Voltage-mode PWM control with input voltage feed-forward for stable regulation on 48 V nominal bus systems
- Supports synchronous rectification by driving external SyncFETs, reducing output rectifier losses in high-current isolated converters
- 20-pin SOIC package integrates controller and drivers, reducing BOM count and PCB area in power supply designs
What is LM5035BMH/NOPB used for?
The LM5035BMH/NOPB is targeted at isolated half-bridge DC-DC converters used in 48 V telecom rectifiers, server power supplies, and base station equipment where high efficiency and compact design are required. Its integrated drivers reduce external component count, making it popular in intermediate bus converters and point-of-load architectures processing up to 200 W. Industrial power modules and distributed power systems also use this controller for its voltage-mode control stability and SyncFET drive capability.

Frequently Asked Questions
What input voltage range is the LM5035BMH/NOPB designed for in typical telecom applications?
The LM5035BMH/NOPB is optimized for a 48 V nominal input bus, with its internal regulators and gate drive supply accepting a bias range of 13 V to 15 V. The 48 V nominal bus is the standard in telecom central office and data center intermediate bus architectures, making this controller a direct fit for those systems without additional pre-regulation.
How does integrating the half-bridge drivers in the LM5035BMH/NOPB reduce system design complexity?
By embedding the high-side and low-side gate drivers for a half-bridge topology directly on the same die as the PWM controller, the LM5035BMH/NOPB eliminates the need for separate gate driver ICs. This integration reduces the component count by at least 2 ICs, shrinks PCB footprint, and lowers the risk of layout-induced noise coupling that commonly affects discrete driver implementations in high-frequency switching converters.
For a 200 W server intermediate bus converter, what package and pin count does the LM5035BMH/NOPB offer?
The LM5035BMH/NOPB is housed in a 20-pin SOIC package, which provides sufficient pins to connect all control, gate drive, sensing, and compensation nodes needed for a complete half-bridge PWM converter without external driver ICs. The SOIC-20 format supports standard automated PCB assembly and is compatible with most server board manufacturing processes.
