LT1976EFE#PBF, Conv DC-DC 2.4V to 60V Step Down Single-Out 1.2V to 54V 3.5A Automotive 16-Pin TSSOP

LT®1976 is a 200KHz monolithic step-down switching regulator that accepts input voltages up to 60V. A high efficiency 1.5A, 0.2ohm switch is included on the die along with all the necessary oscillator, control and logic circuitry. Innovative design techniques along with a new high voltage process achieve high efficiency over a wide input range. Efficiency is maintained over a wide output current range by employing burst mode operation at low currents, utilizing the output to bias the internal circuitry, and by using a supply boost capacitor to fully saturate the power switch. External synchronization can be implemented by driving the SYNC pin with logic-level inputs. The device also has a power good flag with a programmable threshold and time-out and thermal shutdown protection. Typical applications are high voltage power conversion, 14V and 42V automotive systems, industrial power systems, distributed power systems, battery-powered systems.
