LT3991 buck switching regulator

Linear Technology has introduced the LT3991 buck switching regulator IC . The LT3991 supports a wide input voltage range up to 55 volts and a adjustable switching frequency from 200khz to 2Mhz .

The LT3991 operate in low ripple Burst Mode which maintain high efficiency at low output current while the output ripple is below 15 mV .

For fast transient response and good loop stability the LT3991 use an internally compensated current mode topology .
