1. A driver arrangement comprising:
- a high side driver to drive a high side switch of a half-bridge; and
a low side driver to drive a low side switch of said half-bridge;
said low side driver including a low side driver half-bridge having a high side driver switch and a low side driver switch;
wherein a control voltage for said low side driver switch is supplied by a first voltage source, and another control voltage for said high side driver switch is supplied by a second voltage source with a voltage different from a voltage of said first voltage source.
