LT1941
Triple Monolithic
Switching Regulator
FEATURES DESCRIPTION n The LT®1941 is a triple current mode DC/DC converter
with internal power switches. Two of the regulators are
step-down converters with 3A and 2A power switches.
The third regulator can be configured as a boost, inverter
or SEPIC converter and has a 1.5A power switch. All
three converters are synchronized to a 1.1MHz oscillator.
The two step-down converters run with opposite phase,
reducing input ripple current. The output voltages are
set with external resistor dividers and each regulator
has independent shutdown and soft-start circuits. Each
regulator generates a power good signal when its output
is in regulation, easing power supply sequencing and
interfacing with microcontrollers and DSPs. n n Wide Input Range: 3.5V to 25V
