Overview
The MIC2125/6 Demo Board has been developed to demonstrate the capabilities of the MIC2125/6 device with two adaptive ON-time control architectures:
The MIC2125 and MIC2126 Evaluation Boards require only a single power supply with at least 10A current capability. The MIC2125/6 each have an internal VDD LDO, so no external linear regulator is required to power the internal biasing of the IC. In applications with VIN < +5.5V, VDD should be tied to VIN to by-pass the internal linear regulator. The output load can either be a passive or an active load.
The MIC2125/6 Evaluation Boards do not have reverse polarity protection. Applying a negative voltage to the VIN and GND terminals may damage the device. The maximum VIN of the board is rated at 28V.
- Hyper Speed Control® Architecture Enables:
- High delta V operation (VIN = 28V and VOUT = 0.6V)
- High delta V operation (VIN = 28V and VOUT = 0.6V)
- Any Capacitor™ stable
- 4.5V to 28V Input Voltage
- Adjustable Output Voltage from 0.6V to 24V
- 200 kHz to 750 kHz Programmable Switching Frequency
- HyperLight Load® (MIC2125)
- Hyper Speed Control (MIC2126)
- Enable Input and Power Good Output
- Built-in 5V Regulator for Single-Supply Operation
- Programmable Current Limit and “Hiccup” Mode Short-Circuit Protection
- 7 ms Internal Soft-Start, Internal Compensation, and Thermal Shutdown
- Supports Safe Start-Up into a Prebiased Output
- –40°C to +125°C Junction Temperature Range
- 16-pin, 3 mm × 3 mm QFN Package
- 1 x MIC2126YML-20A Eval Board
