Description
BD9A302QWZ is a synchronous buck DC/DCconverter with built-in low on-resistance powerMOSFETs. This IC is capable of providing current upto 3A. The SLLMTM control provides excellentefficiency characteristics in light-load conditions whichmake the product ideal for equipment and devices thatdemand minimal standby power consumption. Theoscillating frequency is high at 1MHz using a smallvalue of inductor. BD9A302QWZ is a current modecontrol DC/DC converter and features high-speedtransient response. Phase compensation can also beset easily.
Features
Single Synchronous Buck DC/DC Converter SLLMTM (Simple Light Load Mode) Control Over Current Protection Short Circuit Protection Thermal Shutdown Protection Under Voltage Lockout Protection UMMP008AZ020 Package(Backside Heat Dissipation)
Typical applications
- Step-Down Power Supply for DSPs, FPGAs, Microprocessors, etc.
- Laptop PCs / Tablet PCs / Servers/ LCD TVs/ Printers, OA Equipment
- Distributed Power Supplies/ Secondary Power Supplies
- Storage Devices (HDDs/SSDs)
