n Flexible Output Voltage Tracking
n Low Dropout: 95% Maximum Duty Cycle
n 5mm × 5mm QFN Package
n FMEA Compliant 38-Pin Exposed Pad TSSOP Package The LT®3992 is a dual current mode PWM step-down
DC/DC converter with two internal 4.6A switches. Independent input voltage, shutdown, feedback, soft-start,
UVLO current limit and comparator pins for each channel
simplify complex power supply tracking and sequencing
requirements. n To optimize efficiency and component size, both converters have a programmable maximum current limit and are
synchronized to either a common external clock input, or …
