The LTC1871EMS#TRPBF is a current mode boost, flyback, or SEPIC controller from Analog Devices, designed to drive an N-channel power MOSFET with minimal external components. It features a wide input voltage range of 2.5V to 36V and eliminates the need for a current sense resistor by utilizing the power MOSFET's on-resistance for improved efficiency.
This controller supports a programmable operating frequency from 50kHz to 1MHz, which can also be synchronized to an external clock. It offers user-controlled pulse skip or Burst Mode operation, making it suitable for battery-operated systems with a low shutdown quiescent current of 10μA. The device includes an internal 5.2V low dropout voltage regulator and output overvoltage protection.
The LTC1871EMS#TRPBF is available in a compact 10-lead MSOP package, ideal for low to medium power applications such as telecom power supplies and portable electronic equipment. Its current mode control provides excellent transient response, and it boasts a high maximum duty cycle of 97%.
Key electrical specifications include a typical output voltage of 5.2V and a typical output current of 20A. The operating temperature range is -40°C to +85°C. The device also features a typical operating supply current of 0.25mA and a shutdown quiescent current of 10μA.
