The LTC3261HMSE#PBF is a fully integrated, high power and high efficiency DC/DC switching regulator. This regulator offers two outputs and is designed to deliver a maximum of 25A and up to 1MHz switching frequency. It is designed to operate from a wide input voltage range of 4V to 28V. The device has a high efficiency of up to 95%, making it ideal for applications requiring high current, high efficiency and low noise.The LTC3261HMSE#PBF has a wide operating temperature range of -40°C to +85°C, making it suitable for use in harsh environments. This regulator also features overvoltage, overcurrent, and thermal shutdown protection. In addition, the LTC3261HMSE#PBF includes internal catch diodes for both the high and low side switches, allowing for greater efficiency and lower power dissipation.The LTC3261HMSE#PBF is suitable for use in a variety of applications, making it an ideal choice for applications that require high power and high efficiency. These applications include industrial and automotive equipment, server power supplies, base station power supplies, power conditioning systems, distributed power systems, and distributed power distribution applications.The LTC3261HMSE#PBF uses a synchronous buck topology with a fixed switching frequency of 1MHz. The device uses a pulse-width modulation scheme (PWM) to regulate output voltage, and an active emitter-controlled (AEC) current mode to regulate the current. The AEC current mode provides faster transient response, higher efficiency, and improved load regulation.The LTC3261HMSE#PBF can be configured to operate in one of three modes: switched-mode operation, pulse-by-pulse control, and a soft start mode. In switched-mode operation, the device operates at a fixed switching frequency and duty cycle, while in pulse-by-pulse control mode, it can change the duty cycle dynamically with an external voltage reference. The soft start mode provides a gentle start-up and inrush current protection.The LTC3261HMSE#PBF also includes a slew rate control feature, which simplifies the control of the output voltage ramp-up and transient response when operating from input voltages that can change rapidly, such as when powering from batteries. The LTC3261HMSE#PBF is available in several packages to suit a wide range of applications, including leadless packages, TDFN and DFN packages, 10-lead MSOP packages, and 16-lead exposed paddle packages.In summary, the LTC3261HMSE#PBF is a fully integrated, high power, high efficiency DC/DC switching regulator. It is designed to operate efficiently from wide input voltages, has a wide operating temperature range, and provides an array of protection features. It is suitable for a variety of applications and offers various modes of operation.
