The LTC3862HUH-2 is an advanced DC-DC Switching Controller with integrated high side n-channel MOSFET and PWM/PFM control functionality. It operates from 4.5V to 14V input voltage and features a wide output voltage range of 0.625V to 18V. The highly integrated architecture of the LTC3862HUH-2 reduces design complexity and facilitates the implementation of a small and cost effective solution for power conversion applications.

The LTC3862HUH-2 is suitable for a wide range of DC-DC converter applications, such as offline power supplies, distributed power systems, and power supplies for industrial, telecom, computer, and automotive markets. It takes advantage of the latest resonant, synchronous, and non-sync technologies to provide maximum design flexibility with minimum external components.

With a highly integrated architecture, the LTC3862HUH-2 simplifies power supply design. The integrated high side MOSFET, which is capable of 1A continuous current, significantly reduces external component count. The design also includes a built-in synchronous demob blocking switch for low input voltage applications, and an adjustable output disconnect threshold for safety-critical applications. Moreover, the IC\'s dual current-mode control architecture offers two levels of pulse-width modulation (PWM) and pulse-frequency modulation (PFM) control for low output voltage applications. This makes the LTC3862HUH-2 the ideal choice for applications requiring accurate and consistent regulation, high power efficiency and small form factor.

The LTC3862HUH-2 also features on-chip protection, making it suitable for applications subject to abnormally high output voltage, output current, and junction temperature. The protection features include overvoltage, overcurrent, and overtemperature protection. Furthermore, the IC provides a minimum load detection output feature that helps prevent loss of regulation due to a minimum load requirement.
