HA17384 Datasheet (Hitachi Semiconductor) - High Speed Current Mode PWM Controller

HA17384, High Speed Current Mode PWM Controller

The HA17384S/H and HA17385H are PWM control switching regulator IC series suitable for highspeed, current-mode switching power supplies.

With ICs from this series and a few external parts, a small, low cost flyback-transformer switching power supply can be constructed, which facilitates good line re
