Tiny High Efficiency 2A Buck Regulator Directly Accepts Automotive, Industrial and Other Wide Ranging Inputs Introduction 2.4MHz

LDESIGN FEATURES Tiny High Efficiency 2A Buck Regulator Directly Accepts Automotive, Industrial and Other Wide Ranging Inputs Introduction 2.4MHz by using a resistor tied from the RT pin to ground. This allows a trade off between component size and efficiency. The switching frequency can be synchronized to an external clock for noise sensitive applications. An external resistor divider programs Automotive batteries, industrial power supplies, distributed supplies and wall transformers are all sources of wide-ranging, high voltage inputs. The easiest way to step down these sources is with a high voltage monolithic stepdown regulator that can directly accept a wide input range and produce a well-regulated output. The LT3480 LT3480 is a new step-down regulator that accepts input from up to 38V (60V transient) while providing excellent line and load regulation and dynamic response. The LT3480 LT3480 offers high efficiency solutions over wide load range and keeps the output ripple low during Burst Mode® operation. The LT3480 LT3480 is a new step-down regulator that accepts input from up to 38V (60V transient). the output voltage to any value above the part's 0.8V reference. The LT3480 LT3480 offers soft-start via a resistor and capacitor on the RUN/SS pin, thus reducing maximum inrush currents during start-up. The LT3480 LT3480 can withstand a shorted output. A cycle-by-cycle internal current limit protects the circuit in overload and limits output power; when the output voltage is pulled to ground by a hard short, the LT3480 LT3480 reduces its operating frequency to limit dissipation LT3480 LT3480 Features Available in either a 10-pin MSOP or a 3mm × 3mm DFN package, the LT3480 LT3480 offers an integrated 3.5A power switch and external compensation for design flexibility. The LT3480 LT3480 employs a constant frequency, current mode architecture. The switching frequency can be set between 250kHz and by Kevin Huang and peak switch current. This lower frequency allows the inductor current to safely discharge, thus preventing current runaway. The high side bootstrapping boost diode is integrated into the IC to minimize solution size and cost. When the output voltage above 2.5V, the anode of the boost diode can be connected to output. For output voltages lower than 2.5V, the boost diode can be tied to a separate rail or to the input (
