توضیحات
The APW7159A is a dual channel voltage mode and synchronous PWM controller which drives dual N-channel
MOSFETs. The two channels are operated with 180 degree phase shift.
The device integrates all of the control, monitoring, and
protecting functions into a single package; provides two
controlled power output with over-voltage, overtemperature, and over-current protections.
The APW7159A provides excellent regulation for output
load variation. The internal 1.0V temperature-compensated reference voltage provides high accuracy of 0.8%
over line and temperature. The device includes a 50kHz
free-running triangle-wave oscillator that is adjustable
from 50kHz to 400kHz.
