Abstract: A driver including first and second buffers connected in parallel between a power source and a return path. In one configuration, the buffer outputs are commonly connected to an external coil and optionally a capacitive load. In another configuration, the buffers' outputs independently drive first and second external transistors. The external transistors are in series between a supply voltage source and its return path.

Abstract: A sample and hold circuit is provided which includes first and second input circuits adapted to sample, respectively, first and second voltage measurements. The second voltage measurements correspond to current measurements. A multiplexer coupled to the first and second input circuits selected either the first or second measurements. A voltage sealer is provided between the output of the first input circuit and the multiplexer. A multiplier circuit, which may be a switched capacitor network, is utilized to multiply the second voltage measurements. The multiplexer provides its output to an analog-to-digital converter.

Abstract: A control system and method for simultaneously regulating the operation of a plurality of different types of switching power converters. The system utilizes in regulating the power converters sampled data and nonlinear feedback control loops.
