Additional Infomation About Product

Datasheet 1.75V to 4.5V, 10mA 1ch Synchronous Boost DC/DC Converter BU33DV5G General Description Key Specifications The BU33DV5G devices provide a power supply solution for products powered by either two-cell alkaline, Input voltage range: 1.75V to 4.5V NiCd or NiMH, or one-cell Li-ion or Li-polymer battery. Output voltage range: 3.23V to 3.37V Output currents can go as high as 10mA while using Average output Current: 10mA(Max.) two alkaline, and discharge it down to 1.8 V. Switching frequency: 100KHz(Typ.) The boost converter is based on a fixed frequency, Standby current: 250A (Typ.) Pulse-width-modulation (PWM) controller using a Power-OFF Circuit Current 1.0A (max) synchronous rectifier to obtain maximum efficiency. The Operating temperature range: -25 to +85 maximum peak current in the boost switch is typically limited to a value of 10 mA. BU33DV5G output voltage is fixed by an internal resistor divider. The device is packaged in a 5-pin small SSOP5 package.
