Soft-Start Capability
Small 10-Pin Thermally Enhanced MSOP and
(3mm × 3mm) DFN Packages The LT®1912 is an adjustable frequency (200kHz to 500kHz)
monolithic step-down switching regulator that accepts
input voltages up to 36V. A high efficiency 0.25Ω switch
is included on the die along with a boost Schottky diode
and the necessary oscillator, control and logic circuitry.
Current mode topology is used for fast transient response
and good loop stability. The LT1912 allows the use of
ceramic capacitors resulting in low output ripple while
keeping total solution size to a minimum. The low current …
