The LT8610EMSE#PBF is a compact, high-efficiency, high-speed synchronous monolithic step-down switching regulator from LT. It consumes only 2.5µA of quiescent current and features a wide input voltage range from 3.4V to 42V.
This regulator includes top and bottom power switches and minimizes 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 10mV 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.
The EN/UV pin has an accurate 1V threshold and can be used to program VIN undervoltage lockout or to shut down the LT8610, reducing the input supply current to 1µA. A capacitor on the TR/SS pin programs the output voltage ramp rate during start-up. The PG flag signals when VOUT is within ±9% of the programmed output voltage as well as fault conditions.
The LT8610EMSE#PBF is available in a small 16-lead MSOP package with an exposed pad for low thermal resistance, suitable for surface mounting. Applications include automotive and industrial supplies, and general-purpose step-down power supplies.
The input voltage range is 3.4V to 42V.
The quiescent current in Burst Mode is 2.5μA.
The typical efficiency is 96% when regulating 5VOUT from 12VIN at 1A.
The minimum switch-on time is 50ns.
The dropout voltage is 200mV at 1A.
The switching frequency can be adjusted from 200kHz to 2.2MHz.
The enable pin has an accurate threshold of 1V.
