The LTC3880EUJ#TRMPBF is a DC DC switching controller that is applicable to a variety of power-conversion applications. It is a phase-shift or hysteretic style synchronous-rectifier controller that regulates the output voltage in flyback, forward and bridge converters. This controller offers an adjustable level of current-limit protection, cycle-by-cycle current limit, adjustable soft-start and input-under voltage lockout, which can be used to enhance the protection of both the load and the converter. Additionally, this device features an internal frequency control loop allowing for operation from 200kHz to 600kHz.

The LTC3880EUJ#TRMPBF provides users with a low component count conversion solution that is highly efficient, accurate, and reliable. With its on-chip clock frequency a flexible operating frequency range is capable, allowing for current mode control as well as voltage mode control. In addition, its integrated synchronous rectifier predriver and control circuitry enables low component count, simple circuitry and highest efficiency.

The working principle of the LTC3880EUJ#TRMPBF is based on the concept of synchronous rectification. Synchronous rectification is a process in which not just one but both switches within the inverter are alternately on and off. This technique allows both switches to act as diodes in the presence of an alternating current. The device works in this manner to enable efficient power conversion and higher power delivery in both buck and boost mode applications.

The LTC3880EUJ#TRMPBF is utilized in many specialized applications. Examples include, but are not limited to, general ac-dc conversion for applications such as LED lighting, plasma display power supplies, telecom power supplies, dc-dc converters and motor drives. This component is especially beneficial when the input voltage is relatively high but the output voltage is relatively low. Its low component count and accurate regulation of the output voltage make it an ideal option for these types of applications.

The LTC3880EUJ#TRMPBF is best suited for applications that require high efficiency and reliability. Its wide operating frequency allows users to control both current and voltage and its integrated synchronous rectifier circuitry enables optimal performance, efficiency and reliability. Its built in frequency control loop, adjustable current limit and soft start operation ensure superior regulation and output voltage accuracy. Additionally, its protection options offer both the load and the converter enhanced protection. This device provides users with a low cost, low component count solution that is highly efficient and reliable, making it an ideal choice for numerous applications.
