Analog Devices / Maxim Integrated MAX668EVKIT Evaluation Kit
Analog Devices MAX668EVKIT Evaluation Kit provides a demonstration platform for the MAX668 Constant-Frequency Pulse-Width-Modulation (PWM) Step-Up Controller combined with an external N-channel MOSFET and Schottky Diode to provide a regulated output voltage. The evaluation kit accepts a +3V to VOUT input and converts it to a +12V output for currents up to 1A, with greater than 90% conversion efficiency. The evaluation kit operates at 500kHz, allowing the use of small external components. The kit is a fully assembled and tested surface-mount circuit board.
The Analog Devices MAX668EVKIT can also evaluate the MAX669 for input voltages below 3V and down to 1.8V. The MAX669 must continuously operate in bootstrapped mode.
