Linear Technology DC102 Demo Manual

DESCRIPTIO
This demonstration circuit is an N-channel half-bridge for
general purpose applications. The half-bridge can be driven
with TTL/CMOS level signals into an LT
drives the N-channel MOSFETs. A self-contained high-
side driver regulator allows PWM operation to 100% duty
cycle without discontinuities. By adding a controller IC and
