Synchronous buck regulator

16 August 2017 Power Electronics / Power Management

Analog Devices, which recently acquired Linear Technology, announced the LT8607, a 750 mA, 42 V input synchronous step-down switching regulator. A unique synchronous rectification topology delivers 93% efficiency while switching at 2 MHz, enabling designers to avoid critical noise-sensitive frequency bands such as AM radio while using a very compact solution footprint. Burst Mode operation keeps quiescent current under 3 μA in no-load standby conditions, ideal for always-on systems. The device’s internal 1,2 A switches deliver up to 750 mA of continuous output current, and it maintains a minimum dropout voltage of only 250 mV (at 500 mA) under all conditions. Spread spectrum frequency modulation and special design techniques ensure low EMI operation.
