LT3506/LT3506A
Dual Monolithic 1.6A
Step-Down Switching Regulator
FEATURES DESCRIPTION n The LT®3506 is a dual current mode PWM step-down DC/DC
converter with internal 2A power switches. Both converters are synchronized to a single oscillator and run with
opposite phases, 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. Wide Input Voltage Range, 3.6V to 25V
