ROHM BD9B300MUV | Demoboard BD9B300MUV-E2EVK-101
Evaluation Board for ROHM's BD9B300MUV Synchronous Buck DC/DC Converter with Integrated FET
Overview
| Topology | Buck Converter |
| Input voltage | 2.7-5 V |
| Switching frequency | 1000-2000 kHz |
| Output 1 | 3.3 V / 3 A |
| IC revision | 00 |
Description
This evaluation board has been specifically developed to evaluate the BD9B300MUV synchronous buck DC/DC converter withintegrated 35mΩ Pch high-side and Nch low-side power MOSFETs. Features include up to 3A output and variable switching frequency:1MHz (FREQ pin connected to VIN) or 2MHz (FREQ pin connected to ground). Multiple protection functions are also built in, including afixed soft start circuit that prevents inrush current during startup, UVLO (Under Voltage Lock Out), TSD (Thermal Shutdown), OCP(Over Current Protection), and SCP (Short-Circuit Protection). An EN pin allows for simple ON/OFF control of the IC to reduce standbycurrent consumption, while a MODE pin that enables users to select fixed frequency PWM mode or Deep-SLLM control thatautomatically switches between modes.
Typical applications
- Step-Down Power Supplies for DSPs, FPGAs, Microcontrollers, and more,Distributed and Secondary Power Supplies
- Laptop PCs/Tablet PCs/Servers,LCD TVs,Printers, OA Equipment,Entertainment Devices
- Storage Devices (HDDs/SSDs)
