Part Number: MIC28304-1-5V-EV
MIC28304-1 5V EVALUATION BOARD
- Input: 7V to 70V
- Output: 0.8V to 5V at 3A
- 600kHz Switching Frequency (Adjustable 200kHz to 600kHz)
Overview
The MIC28304 is synchronous step-down regulator module, featuring a unique adaptive ON-time control architecture. The module incorporates a DC-to-DC controller, power MOSFETs, bootstrap diode, bootstrap capacitor, and an inductor in a single package. The MIC28304 operates over an input supply range of 4.5V to 70V and can be used to supply up to 3A of output current. The output voltage is adjustable down to 0.8V with a guaranteed accuracy of ±1%. The device operates with a programmable switching frequency from 200kHz to 600kHz.
The MIC28304-1 has the HyperLight Load® architecture, so it can operate in pulse skipping mode at light load. However, it operates in fixed frequency CCM mode from medium load to heavy load. The MIC28304-2 has Hyper Speed Control™ architecture, which operates in fixed frequency CCM mode under all load conditions.
N/A
The MIC28304-1 and MIC28304-2 evaluation board requires only a single power supply with at least 10A current capability. No external linear regulator is required to power the internal biasing of the IC because the MIC28304 has internal PVDD LDO. In the applications with VIN < +5.5V, PVDD should be tied to VIN to bypass the internal linear regulator. The output load can either be a passive or an active load.
