Here's a thought.

A PWN can be used with just about circuit. Right? Right.
On the PWM exit, use a power transistor . TIP32 for an example. Rated 3A.
Feed the base with the PWM signal, you'll get a shitf between active and cut zones within a certain frequency limits. The transistor must have a good response time. He'll reproduce the wave (with a slight deformation) , but the current will only depend on the power transistor itself and the power supply.
