The LTC3862EGN-1 is a high-performance member of the PMIC - Voltage Regulators - DC DC Switching Controllers family of products. The device is designed to provide reliable and efficient power conversion solutions in a wide range of applications. It is equipped with an integrated high-side MOSFET and a low-side MOSFET, allowing for efficiency improvements in DC-to-DC converters. The integrated monitoring circuitry ensures reliable operation, and several protection features are included to guard against over-current, over-temperature, and short-circuit conditions.

The LTC3862EGN-1 is a synchronous step-down converter designed for easily configurable, low-cost and efficient conversion from input voltages up to 38V. It has an adjustable output voltage from 0.8V to 21V with 1% accuracy over temperature. It can deliver up to 150mA of output current, and features an internal soft-start circuit, programmable input undervoltage lockout and output overvoltage protect. Internal gate drivers provide fast switching performance and reduce external component count. The integrated power switches are also protected against over-current and over-temperature conditions.

The LTC3862EGN-1 utilizes a hysteretic Control-L Topology with an external compensation network to ensure fast transient response and excellent line and load regulation. The switching frequency is adjustable through an external resistor, allowing for optimization of efficiency and noise performance. The converter is shut down when the EN/UVLO pin voltage is below the programmed UVLO threshold, or when the OTW/SS pin voltage is below 0.4V. The device can be configured as a non-synchronous buck converter via the SY/SLV pin, allowing for reduction of output ripple and improved efficiency.

The LTC3862EGN-1 is a flexible and highly configurable device designed to provide reliable and efficient power conversion solutions. It is ideal for designing efficient and cost-effective DC-to-DC converters for a wide range of applications, and its excellent performance and features ensure efficient and reliable operation even in the most demanding environments.
