Simple Circuit Provides +5 Volt Gate Bias From  48 Volt Input: Maxim Application Note #1803

Simple circuit provides 5V gate bias from –48V: 09/19/2002  EDN - Design Ideas /  A small and simple circuit derives 5V from the -48V rail that telecomm applications typically use (Figure 1). Useful for gate bias and other purposes, the 5V supply delivers as much as 5-mA output current. A shunt reference, IC1, defines -5V as ground reference for a charge pump, IC2. The charge pump doubles this 5V difference betw1een system ground and charge-pump ground to produce 5V with res....
