Simple buck converter with 2n7000 mosfet and gate drive from a signal-generator

I have been thinking about what would be required to create a switch-mode analog MPPT system to charge a small battery. Ideally, small and low-powered - something suitable for a solar-powered wireless 3.3V ESP8266.

Possible Design

Buck converter

PWM device

Multipiliers are hard!

Some good notes on multipliers can be found in Analog Devices tutorial pdf

Mosfet drivers
