Description

A generic Voltage Mode Boost (step up) Converter to drive a constant current of 10mA through a LED string.

100mV reference voltage with soft start.

Voltage error amplifier.

Pulse width modulator (sawtooth generator and comparator)

Type 3 loop compensation supplied by Rc1, Cc1, Cc2, Rc3 and Cc3 (there is no Rc2!).

Note that compensation is not optimised.
