What are the key features of MIC23201YML-T5?
- 2 A output current capability with 2.7 V to 5.5 V input range covers single-cell Li-ion and USB-powered applications in a 10-pin VDFN package
- 2 MHz PWM switching frequency enables use of sub-1 µH inductors and compact ceramic output capacitors, shrinking overall solution footprint
- Hysteretic start-up control (HSC) prevents output voltage overshoot during power-up, protecting downstream ICs from overvoltage stress
What is MIC23201YML-T5 used for?
The MIC23201YML-T5 is well suited for point-of-load DC-DC regulation in portable devices, USB-powered accessories, and IoT modules operating from single-cell Li-ion batteries in the 2.7 V to 5.5 V input range. Its 2 A output capacity handles processor core voltage rails, DDR memory supplies, and RF transceiver power rails in compact wireless modules. The high 2 MHz switching frequency minimizes external component size, making it ideal for space-constrained wearable and embedded computing designs.

Frequently Asked Questions
What is the input voltage range and output current rating of the MIC23201YML-T5 buck regulator?
The MIC23201YML-T5 operates from a 2.7 V to 5.5 V input voltage range with a nominal input of 3.3 V, and delivers up to 2 A continuous output current. This range covers single-cell Li-ion batteries (2.7 V discharged to 4.2 V charged), regulated 3.3 V USB power rails, and 5 V USB bus power. The 2 A output handles most processor core, memory, and RF transceiver power requirements in portable and embedded designs.
How does the 2 MHz switching frequency of MIC23201YML-T5 reduce external component size compared to lower-frequency buck regulators?
At 2 MHz, the MIC23201YML-T5 allows inductors in the 0.47 µH to 1 µH range compared to 4.7 µH to 10 µH values required at 300 kHz to 500 kHz. Smaller inductance values correspond to physically smaller inductors (0402 or 0603 size), and the output ripple current is more easily filtered by X5R ceramic capacitors of 4.7 µF to 10 µF instead of 22 µF to 47 µF tantalum or aluminum capacitors. Total passive component board area may shrink by 50% or more versus a comparable 300 kHz design.
What is the hysteretic start-up control (HSC) feature in MIC23201YML-T5, and when is it critical?
The hysteretic start-up control (HSC) in the MIC23201YML-T5 regulates the output voltage ramp rate during power-up by limiting the duty cycle increase to a controlled hysteretic band. This prevents the output from overshooting the programmed set point by more than a few millivolts during initial turn-on, which is critical when powering sensitive DSPs, FPGAs, or RF transceivers that specify maximum startup overvoltage below 5% of their nominal supply. Without HSC, uncontrolled inrush into a pre-biased output capacitor could momentarily exceed device absolute maximum ratings.
For a compact BLE sensor module running from a 3.7 V Li-ion cell, why choose MIC23201YML-T5 over a lower-cost LDO regulator?
At 3.7 V input and 1.8 V output at 500 mA load, an LDO regulator dissipates approximately 950 mW as heat, requiring a large thermal area and reducing battery runtime by roughly 50% relative to the buck regulator's theoretical efficiency. The MIC23201YML-T5 achieves greater than 85% efficiency at that operating point, dissipating less than 150 mW, which extends battery life by several hours in typical BLE beaconing applications where average current draw is 20 mA to 100 mA.
