This device features single-rail input support, one
20-mΩ and one 7.5-mΩ integrated MOSFET,
accurate 1%, 0.6 V Reference, and integrated boost
switch. A sample of competitive features include:
greater than 96% maximum efficiency, 3 V to 15 V
wide input voltage range, very low external
component count, D-CAP™ mode control for super
fast transient, selectable auto-skip and PWM
operation, internal soft-start control, adjustable
frequency, and no need for compensation.
