LTC1143/LTC1143L LTC1143L-ADJ Dual High Efficiency SO-16 Step-Down Switching Regulator Controllers DESCRIPTION
The LTC1143 series is a dual step-down switching regulator controller featuring automatic Burst ModeTM operation to maintain high efficiencies at low output currents. This device is posed of two separate regulator blocks, each driving an external power MOSFET at switching frequencies up to 400kHz using a constant off-time current mode architecture. Both fixed and adjustable voltages are available. The operating current level for both regulators is userprogrammable via an external current sense resistor. Wide input supply range allows operation from 4V to 14V (16V maximum). The...
