FAN8841 Datasheet (Fairchild Semiconductor) - Dual Half-Bridge Piezoelectric Driver

FAN8841, Dual Half-Bridge Piezoelectric Driver

The FAN8841 is a single-chip piezoelectric actuator driver consisting of a step-up DC-DC converter with integrated 36 V boost switch and the dual half-bridge output stages.

The step-up DC-DC converter operates in Critical Conduction Mode (CRM) in order to reduce switching loss at the DC-DC converter
