LT3980 5 volt monolithic buck switching regulator

Linear Technology introduces the  LT3980 monolithic buck switching regulator with high efficiency and high input voltage  .  The LT3980 has an adjustable frequency  from 100kHz  to 2.4MHz and accepts input voltages up to 58V  . The transient voltage of the LT3980  is around 80 volts .  The maximum output current which can be delivered by the LT3980  monolithic buck switching regulator is around 2 Amps .

The LT3980  monolithic buck switching regulator is designed in Small 16-Pin Thermally Enhanced MSOP and DFN packages and includes  short-circuit and input overvoltage protection , thermal protection and other features .

Other features integrated in the LT3980 package are 200mΩ switch , Schottky diode and the  necessary oscillator, control, and logic circuitry.

For fast transient response and good loop stability LT3980 use current mode topology .

Main features of the LT3980 monolithic buck switching regulator are : wide input range from 3.6V to 58V , overvoltage lockout protects circuits through 80V transients ,  2A Maximum Output Current , low ripple (<15mVP-P) Burst Mode, aAdjustable switching frequency: 100kHz to 2.4MHz ,low shutdown current: IQ < 1μA ,catch diode current sense protects circuit through short-circuit and input overvoltage , synchronizable between 250kHz to 2MHz , saturating switch design: 200mΩ On-Resistance , thermal protection , Soft-Start Capability .

Like many other regulators manufactured by Linear Technology the LT3980 monolithic buck switching regulator is easy to use in applications and is ideal for compact applications .
