Description
The BD9850FVM is a 1-channel DC/DC step-down switching regulator controller, while the BD9851EFV is a 2-channel DC/DC
step-down switching regulator controller. The BD9850FVM is adaptable for a maximum switching frequency of 2 MHz and the
BD9851EFV for that of 3 MHz. Both provide space saving in all applications.
Features
1) Adaptable for 2-MHz switching frequency (externally variable) (BD9850FVM)
Adaptable for 3-MHz switching frequency (externally variable) (BD9851EFV)
2) FET direct drive
3) High-accuracy reference voltage (Accuracy: ±1%)
4) Built-in Under Voltage Lock Out circuit (UVLO)
5) Built-in Thermal Shutdown circuit (TSD)
6) The BD9851EFV provides two channels:
Channel 1 available for selection of step-down/step-up switching
Channel 2 available for selection of step-down/inverting switching.
7) Compact MSOP8 package (BD9850FVM) / HTSSOP-B20 package (BD9851EFV)
Applications
TFT panel, TA / Router, digital consumer electronics, PC, and portable CD/DVD/DVC
