Micrel, Inc. MIC2203 Ordering Information Part Number Standard Pb-Free Output Voltage Junction Temperature Range Package MIC2203BMM MIC2203YMM Adjustable -40°C to +125°C MSOP-10L MIC2203BML MIC2203YML Adjustable -40°C to +125°C 3mm x 3mm MLF-10L Pin Configuration MSOP-10 (MM) MLF-10 (ML) Top View Pin Description Pin Number Pin Name Pin Function 1 SW Switch (Output): Internal power MOSFET output switches. 2 VIN Supply Voltage (Input): Requires a bypass capacitor to GND. 3 SYNC_IN SYNC_IN for the MIC2203, Sync the main switching frequency to a external clock. Should be tied to ground when not in use. 4 SYNC_OUT SYNC_OUT a 50ns wide sync pulse to feed into SYNC_IN on MIC2203. Can be left open or tied to ground when not used. 5 EN A low level EN will power down the device, reducing the quiescent current to under 1 µA. 6 FB Input to the error amplifier, connect to the external resistor divider network to set the output voltage. 7 BIAS Internal circuit bias supply, nominally 2.3V. Must be de-coupled to signal ground and can have a minimum of external DC loading. 8,9,10 GND Ground EP GND Exposed backside pad, connect to Ground (MLF option only) December 2004 2 M9999-120604 (408) 955-1690 |
