MIC2129 Evaluation Board

The MIC2129 is a wide input voltage range, 4.5V to 100V, Step-down synchronous DC-to-DC controller with Adaptive On-time control architecture. The output voltage is adjustable from 0.6V to DMAX × VIN with ±1% reference accuracy. The selectable gate driver voltage feature allows customers to use either logic level MOSFETs or standard MOSFETs. The precision enable feature allows the user to turn on the MIC2129 at desired input voltage. Internal bootstrap diode eliminates the need for an external bootstrap diode. Output voltage remote sensing feature improves output voltage regulation by compensating for the voltage drop in ground returns in high current applications. The device operates with a programmable switching frequency from 100 kHz to 800 kHz. The MIC2129 is available in 24-pin 4 mm x 4 mm VQFN and 24-pin 7.8 mm x 6.4 mm TSSOP package, with a -40°C to +125°C junction operating temperature range. The 100V rating of this device makes it attractive for applications such as communications, automotive and industrial, which have increasing requirements for additional voltage safety headroom.
