Frequently Asked Questions
What input voltage range and maximum output current does the MIC23303YML-T5 support for battery-powered designs?
The MIC23303YML-T5 operates from a 2.7 V to 5.5 V input supply and can deliver up to 3 A continuous output current. This range makes it compatible with single-cell Li-ion batteries and USB 5 V rails, supporting a wide variety of portable and IoT applications requiring regulated power below 3.6 V output.
How does HyperLight Load mode extend battery life in the MIC23303YML-T5?
HyperLight Load mode switches the MIC23303YML-T5 from 4 MHz PWM to PFM (pulse-frequency modulation) at light loads, dramatically reducing switching losses and quiescent current. This improves efficiency at loads below a few hundred milliamps, extending battery runtime in IoT nodes and wearables where standby and light-load intervals dominate operating time.
What external components are needed when setting the MIC23303YML-T5 output to 1.8 V at 3 A?
At 4 MHz switching frequency, the MIC23303YML-T5 typically requires an inductor of about 1 µH and output capacitors of 10 µF to 22 µF for stable 1.8 V operation at 3 A. The output voltage is set with a resistor divider from the feedback pin, with the adjustable range spanning 0.65 V to 3.6 V as defined in the Microchip MIC23303 datasheet.
