ROHM – Step-Down Switching Regulators With Built-In Power MOSFET BD9G101G
The new switching regulator series designed to meet the high operating voltage, extended temperature, and small layout requirements demanded of today’s high performance, space-constrained power supply applications. Delivering extremely high power efficiency over a wide current load, ROHM’s new switching regulators are optimized to support a comprehensive range of industrial, consumer and battery-powered equipment power supplies. As users demand increased performance from smaller and smaller power supply applications, ROHM’s expanded DC/DC switching regulator line offers significant efficiency advantages over other voltage regulators and permits designers to further shrink board sizes.
ROHM’s BD9G10H DC/DC converter features a high and wide input voltage range (VCC=6V~42V), an integrated internal high-side 42V power MOSFET, and provides 0.5A of DC output.
Feature Sets in Detail:
The BD9G101G gives power supply designers a wide operating voltage range from 6 to 42V with extended operating temperature (-40 to 105C) in a very small SOT23 (SSOP6) package that measures only 2.9×2.8×1.25mm. Its fixed 1.5MHz operating frequency allows the use of small inductors and ceramic capacitors. With a 45V/800mΩ internal power MOSFET that delivers greater efficiency, the BD9G101G delivers 0.75V±1.5% feedback pin voltage and integrates overcurrent protection, under voltage lock out and thermal shutdown functions.
Applications:
- Battery-Powered, Secondary POL, Distributed Power Supplies
- Power supplies in:
- LCD TVs
- Broadband/Communications Equipment
- Printers
- Notebook/Tablet PCs, Servers
- Gaming Equipment
- Storage Devices (HDDs/SSDs)
Evaluation boards supporting the two products are available through distribution.
