Analog Devices Inc. LTC3803HS6-3#TRMPBF

The LTC3803HS6-3#TRMPBF is a high-performance, constant-frequency, current mode PWM controller designed by Analog Devices Inc. for power supply applications. This compact and efficient controller operates at a fixed frequency of 200kHz which provides a predictable noise spectrum, making it an ideal choice for noise-sensitive applications. Crafted with precision, the LTC3803HS6-3#TRMPBF is housed in a small TSOT-23 package, perfect for space-constrained designs.

This advanced PWM controller is tailored for step-down (buck) converters, but its versatility allows it to be used in various topologies such as boost converters, inverting power supplies, and more. The LTC3803HS6-3#TRMPBF is designed to work with a wide range of input voltages, from 4V to 60V, which enables its use in a broad array of power systems, from battery-powered devices to industrial power supplies.

The device features a low start-up voltage of just 100mV, and an operating quiescent current of only 70µA, which significantly enhances the efficiency of the overall power supply, especially in battery-operated systems where power conservation is critical. Furthermore, the LTC3803HS6-3#TRMPBF includes an undervoltage lockout (UVLO) feature that ensures reliable operation by shutting down the controller when the input voltage falls below a predefined threshold.

With its robust design, the LTC3803HS6-3#TRMPBF provides excellent protection features, including cycle-by-cycle current limit and thermal shutdown, safeguarding the controller and the power system from over-current and over-temperature conditions. The device's current mode operation delivers fast transient response and excellent loop stability.

For designers looking for a reliable and high-performing PWM controller, the LTC3803HS6-3#TRMPBF from Analog Devices Inc. is an outstanding choice. Its combination of features, efficiency, and compactness makes it well-suited for a wide range of applications, including telecom power supplies, portable devices, and distributed power systems.

Whether you're designing a new power system or upgrading an existing one, the LTC3803HS6-3#TRMPBF provides the performance and reliability that is synonymous with Analog Devices' products, ensuring that your power supplies operate efficiently and effectively.
