The LTC1871EMS#TRPBF is a current mode boost, flyback, and SEPIC controller manufactured by Analog Devices. It is designed to drive an N-channel power MOSFET and requires minimal external components, making it suitable for low to medium power applications. This controller eliminates the need for a current sense resistor by utilizing the power MOSFET's on-resistance, which maximizes efficiency.
The device operates over a wide input voltage range of 2.5V to 36V and supports programmable operating frequencies from 50kHz to 1MHz. It offers features such as Burst Mode operation for light loads, a low shutdown quiescent current of 10μA, and an internal 5.2V low dropout voltage regulator. The LTC1871EMS#TRPBF provides excellent transient response due to its current mode control and has a high maximum duty cycle of 92% typical.
Available in a compact 10-lead MSOP package, this controller is ideal for battery-operated systems and applications requiring efficient power management. It can be synchronized to an external clock and offers user-controlled pulse skip or Burst Mode operation. The controller also includes output overvoltage protection.
Key specifications include an input voltage range of 2.5V to 36V, an output voltage of 5.2V, and a maximum output current of 20A. The operating temperature range is from -40°C to +85°C. The device is surface-mountable and supplied in cut tape packaging with a standard pack quantity of 2500.
The input voltage range is 2.5V to 36V.
