Analog Devices ADP2230
The ADP2230 includes two high efficiency, low quiescent current, 800 mA, step-down, dc-to-dc converters in a small, 10-lead, 3 mm × 3 mm, LFCSP package. The total solution requires only five tiny external components. When the ADP2230 is used with three 0603 capacitors and two 2 mm × 2 mm inductors, the total solution size is about 48 mm2, resulting in the smallest footprint solution to meet a variety of portable applications.| Part No. | ADP2230 |
