LT8620IUDD#PBF

LT8620 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator. Top and bottom power switches are included with all necessary circuitry to minimize the need for external components. Low ripple burst mode operation enables high efficiency down to very low output currents while keeping the output ripple below 10mVP-P. P. A SYNC pin allows synchronization to an external clock. Internal compensation with peak current mode topology allows the use of small inductors and results in fast transient response and good loop stability. It is widely used in application such as automotive and industrial supplies, general purpose step-down, GSM power supplies etc.
