LTC1142HVCG-ADJ - Brand New Linear Technology DC DC Switching Controllers
-
Description
The LTC1142HVCG-ADJ is a dual synchronous step-down switching regulator controller that features automatic Burst ModeTM operation to maintain high efficiencies at low output currents. It is composed of two separate regulator blocks, each driving a pair of external complementary power MOSFETs, at switching frequencies up to 250kHz, using a constant off-time current mode architecture providing constant ripple current in the inductor.
