Precision Stepper Motor Driver

Description The PBL 3771/1 is a switch-mode, constant-current driver IC (chopper) with two channels, one for each winding of a two-phase stepper motor. The circuit is especially developed for use in microstepping applications in conjunction with the matching dual DAC (Digital-to-Analog Converter)

LOW-POWER OFF-LINE PRIMARY SIDE REGULATION CONTROLLER

Description The AP3771 is a high performance AC/DC power supply controller for battery charger and adapter applications. The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supplies. The AP3771 provides accurate constant voltage,
