Abstract:
An electronic circuit, referred to as an on-time extension circuit herein, provides an ability to adjust a power delivered to a load by pulsing a predetermined current to the load. The on time of the a DC-DC converter used to provide the power is extended to be longer than the on time of the current pulse when the on time of the current pulses becomes very short.
