A DC to DC converter for converting an input DC voltage to an output DC voltage. The DC to DC converter may include at least one switch, an inductor coupled to the at least one switch, and a controller capable of providing a control signal. The at least one switch may be responsive to the control signal in a first state to enter an ON state for an ON time interval, the ON time interval based on the input DC voltage and a constant. An electronic device including such a DC to DC converter and related methods are also provided.

Boost converter with enhanced control capabilities of emulating an inductor current

A differential driving circuit is provided that reduces ripple current. The differential driving circuit is operable to supply a linear current in a low current mode and a PWM current in a high current mode. Depending on the direction of current flow through the load, heating and cooling is provided for loads such as a thermal electric cooler.
