Analog Devices LT8607 | Demoboard AD-GMSLCAMRPI-ADP
42V, 750mA Synchronous Step-Down Regulator with 2.5µA Quiescent Current
Overview
| Topology | Other Topology |
| Input voltage | 3-42 V |
| Switching frequency | 200-2200 kHz |
| Output 1 | 3.3 V / 0.5 A |
Description
The LT®8607 is a compact, high efficiency, high speed syn-chronous monolithic step-down switching regulator that consumes only 1.7µA of non-switching quiescent current. The LT8607 can deliver 750mA of continuous current. Burst Mode operation enables high efficiency down to very low output currents while keeping the output ripple below 10mVP-P. 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 LT8607reducing the input supply current to 1µA.
