LTC1872BES6#TR Step-Up DC/DC Converter

The LTC1872BES6#TR from Linear Technology is a high-performance, constant-frequency, step-up DC/DC converter that is designed to provide a compact and efficient power management solution for a wide range of applications. This device is part of Linear Technology's family of monolithic, synchronous, step-up switching regulators that provide high efficiency over a broad range of load currents.

Housed in a space-saving SOT-23 package, the LTC1872BES6#TR features a low quiescent current and a wide input voltage range of 2.6V to 16V, making it suitable for applications powered by single-cell Li-Ion batteries, multiple Alkaline/NiMH cells, or standard 3.3V and 5V power rails. With its capability to convert input voltages to higher output voltages up to 34V, this converter is ideal for driving OLED displays, CCDs, white LEDs, and other devices requiring a high voltage supply.

The LTC1872BES6#TR utilizes a constant-frequency, current mode architecture that provides excellent line and load regulation, along with a predictable switching frequency. This makes it easier to filter out noise and to manage electromagnetic interference (EMI), which is critical in noise-sensitive applications. Its low RDS(ON) internal switches contribute to a high efficiency of up to 94%, minimizing heat generation and allowing for a smaller overall solution size.

In addition, the LTC1872BES6#TR offers a range of features that enhance the performance and safety of the powered system. These include programmable soft-start to control inrush current during startup, a shutdown mode that reduces supply current to less than 1µA, and thermal shutdown and current limit protection to prevent damage under abnormal operating conditions. The device also supports synchronization to an external clock, which allows for the reduction of RF interference when used in sensitive applications.

Overall, the LTC1872BES6#TR is a versatile and reliable choice for designers looking to implement a compact, high-efficiency power supply solution. Its robust feature set and small form factor make it an excellent option for portable electronics, industrial controls, medical devices, and other systems where space and power efficiency are critical.
