ABSTRACT:
An multi-stage error amplifier (22) of a power management system (10) is formed to insert a zero to compensate for a high frequency pole that could cause unstable outputs at some output current levels. The error amplifier (22) includes a feed-forward block (40) that isolates the capacitor (36) from other signal paths to facilitate low noise and high efficiency operation.
