BD9B200MUV-E2

The BD9B200MUV-E2 from ROHM is a 2.7V to 5.5V Input, 2an integrated MOSFET single synchronous buck DC to DC converter in 16 pin VQFN package. BD9B200MUV is a synchronous buck switching regulator with built-in low on-resistance power MOSFETs. This IC is capable of providing current up to 2A, 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 step-down power supply(for DSPs, FPGAs, microprocessors), laptop PCs/tablet PCs/servers, LCD TVs, storage devices (HDDs/SSDs), printers, OA equipment, entertainment devices 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 50mohm (typ), low-side MOSFET ON resistance is 50mohm (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
