Step-down dc/dc converter
The LT8608, a 1.5 A synchronous step-down dc/dc converter, delivers 93& efficiency at 2 MHz and operates from 3.0 V to 42 V inputs. . The LT8608 maintains a minimum dropout voltage of only 200 mV (@500 mA) under all conditions, enabling it to excel in applications such as automotive cold-crank. The LT8608’s 10-lead thermally enhanced MSOP package and high switching frequency keeps external inductors and capacitors small, providing a compact, thermally efficient footprint. The LT8608 utilizes internal top and bottom high efficiency power switches with the necessary boost diode, oscillator, control and logic circuitry integrated into a single die.
