9% of regulation and facilitates output voltage monitoring and supply sequencing. When set in shutdown (EN = GND), the MIC23350 device draws a typical current of 1.5 µA. MIC23350 is available in a thermally efficient, 16-lead 2.5 mm x 2.5 mm x 0.55 mm thin FTQFN package, with an operating junction temperature range from -40°C to +125°C. -
Page 8: What Is The Mic23350 Evaluation Board
Product Overview WHAT IS THE MIC23350 EVALUATION BOARD? The MIC23350 Evaluation Board is used to evaluate and demonstrate the MIC23350 device. This board demonstrates the MIC23350 device in a buck converter application, supplied from an external voltage source (from 2.4V to 5.5V), to a pin-programmed regulated output. -
Page 9: Chapter 2. Installation And Operation
Chapter 2. Installation and Operation INTRODUCTION MIC23350 has been developed for applications suited for 2.4V to 5.5V input voltage range, low shutdown and quiescent currents, 3A continuous output current. This makes the MIC23350 device ideal for single cell Li-Ion battery-powered applications. The 100% duty cycle capability provides low-dropout operation, extending the operating range in portable systems. -

- Page 13 First, the input and output capacitors should be placed as close to the MIC23350 device as possible, and on the same layer as the IC. This ensures low ripple and improved performance. Secondly, vias must be used under the MIC23350 device, from its exposed pad to the GND plane, in order to allow for best heat dissipation.
