Differential load driver circuits |
摘要 |
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.
