Datasheet Switching Regulators (Integrated FET) 3.3V and 5V output Low Iq DC/DC Converters BD99010EFV-M BD99011EFV-M General Description Key Specifications The BD99010EFV-M and BD99011EFV-M are ultra low Iq Input Voltage Range: 3.6V to 35V Step-down DC/DC converters with integrated power (Absolute Maximum42V) MOSFETs for 3.3V and 5V, respectively. (Initial startup is over 3.9V) The SLLMTM (Simple Light Load Mode) control ensures Output Voltage Range: 3.3V (BD99010EFV-M) an ultra low quiescent current and high efficiency at low 5V (BD99011EFV-M) load situation as well as a high efficiency at high load Switch Output Current: 2A(Max) situations while maintaining a regulated output voltage. Switching Frequency: 200kHz to 500kHz The product is compliant with automotive standards and Pch FET ON Resistance: 170m(Typ) accommodates a maximum voltage of 42V. The minimum Nch FET ON Resistance: 130m(Typ) input voltage is 3.6 V in order to sustain output at cold Operating Temperature Range: -40C to +105C cranking conditions. The current mode regulation loop AEC-Q100 Qualified gives a fast transient response and easy phase compensation. The BD99010EFV-M and BD99011EFV-M are available Package W(Typ) x D(Typ) x H(Max) in a HTSSOP-B24 package. In an application it requires a HTSSOP-B24 7.80mm x 7.600mm x 1.00mm small number of external components and small PCB footprint. Features Low Quiescent Operating Current: 22A Simple Light Load Mode (SLLM) Supports Cold Cranking Down to 3.6V Output Voltage Accuracy: 2% Synchronous Rectifier Soft Start Chip Enable pin compatible with CMOS logic and battery voltages Forced PMW Mode Function Current Mode Control with External Compensation Circuit Applications Over Current Protection, Short Circuit Protection, Automotive Battery Powered Supplies(Cluster Panel, Over Voltage Protection for VOUT, Under Voltage Car Multimedia) Lock Out for VIN and Thermal Protection Circuits Industrial/Consumer Supplies.
