Product Overview

The BD9B301MUV-LBE2 from ROHM is a 2.7V to 5.5V input, 3an integrated MOSFET single synchronous buck DC to DC converter in 16 pin VQFN package. This IC provides long time support in industrial market. BD9B301MUV-LB is a synchronous buck switching regulator with built-in low on-resistance power MOSFETs. This IC is capable of providing current up to 3A, features fast transient response by employing constant on-time control system. It offers high oscillating frequency at low inductance. With its original constant on-time control method which operates low consumption at light load, this product is ideal for equipment and devices that demand minimal standby power consumption. Typical applications include industrial equipment, step-down power supply(for DSPs, FPGAs, microprocessors), storage devices (HDDs/SSDs), printers, OA equipment and distributed power supplies/secondary power supplies.
  • Output voltage range from 0.8V to VPVIN x 0.8V
  • Switching frequency is 2MHz/1MHz (typ), standby current is 0µA (typ)
  • High-side MOSFET ON resistance is 35mohm (typ), low-side MOSFET ON resistance is 35mohm (typ)
  • Over current protection
  • Short circuit protection
  • Thermal shutdown protection
  • Under voltage lockout protection
  • Adjustable soft start
  • Power good output
  • Constant on-time control suitable to deep-SLLM
