Switching Regulator
with MOSFET for DDR-SDRAM Cores
BD95500MUV
No.10030ECT21
●Description
BD95500MUV is a switching regulator with high output current (up to 6A) which can achieve low output voltage
(0.7V to 5.0V) from a wide input voltage range (3V to 20V). High efficiency for the switching regulator can be realized by
utilizing an internal N-MOSFET power transistor. A new technology called H³Reg^TM is a Rohm proprietary control method to
realize ultra high transient response against load change. SLLM (Simple Light Load Mode) technology is also integrated to
improve efficiency in light load mode, providing high efficiency over a wide load range. For protection and ease of use, the
soft start function, variable frequency function, short circuit protection function with timer latch, over voltage protection
function, and power good function are all built in. This switching regulator is specially designed for sets of various kinds.
●Features
1) Integrated low ON resistance N-MOSFET (TYP. 50mΩ)
2) H³Reg^TM DC/DC converter controller
3) Adjustable Simple Light Load Mode (SLLM), and forced continuous mode
4) Thermal Shut Down (TSD), Under Voltage LockOut (UVLO), Adjustable Over Current Protection (OCP),
Over Voltage Protection (OVP), Short Circuit Protection(SCP) built-in
5) Soft start function to minimize rush current during startup
6) Adjustable switching frequency (f=200KHz～1000KHz)
7) Built-in output discharge function
8) VQFN040V6060 Package
9) Tracking Function
10) Integrated boot strap diode
11) Power Good function
●Applications
Mobile PC, Desktop PC, LCD-TV, Digital Components, etc
