Microchip Technology MIC23159
The MIC23159 also provides an auto-discharge feature that switches in a 225Ω pull-down circuit on its output to discharge the output capacitor when disabled. The 20-pin 3 mm x 4 mm QFN package saves precious board space and requires seven external components for each channel. The MIC23158/9 is designed for use with a very small inductor, down to 0.47 µH, and an output capacitor as small as 2.2 µF that enables a total solution size, less than 1 mm in height.| Part No. | MIC23159 |
