Additional Infomation About Product

Datasheet 4. 5V to 5.5V, 2.0A 1ch Synchronous Buck Converter with Integrated FET BD9111NV General Description Key Specifications The BD9111NV is ROHMs high efficiency step-down Input Voltage Range: 4.5V to 5.5V switching regulator designed to produce a voltage as Output Voltage: 3.3V(Typ) low as 3.3V from a supply voltage of 5V. It offers high Output Current: 2.0A (Max) efficiency by using pulse skip control technology and Switching Frequency: 1MHz(Typ) synchronous switches, and provides fast transient Pch FET ON Resistance: 200m(Typ) response to sudden load changes by implementing Nch FET ON Resistance: 150m(Typ) current mode control. Standby Current: 0A (Typ) Operating Temperature Range: -25C to +105C Features Package W(Typ) x D(Typ) x H(Max) Fast Transient Response because of Current Mode PWM Control System High Efficiency for All Load Ranges because of Synchronous Switches (Nch and Pch FET) and TM SLLM (Simple Light Load Mode) Soft-Start Function Thermal Shutdown and UVLO Functions Short-Circuit Protection with Time Delay Function Shutdown Function Applications Power Supply for LSI including DSP, Microcomputer and ASIC SON008V5060 5.00mm x 6.00mm x 1.00mm Typical Application Circuit L CIN V CC VCC,PVCC EN SW V OUT V VOUT OUT C O ITH GND,PGND RITH CITH Figure 1.
