Description

  • DC328A, Demonstration Board using LTC1872ES6 constant frequency current mode step-up DC/DC controller. The DC328A is capable of providing 1A at an output voltage of 5V from a single Li-Ion cell. It is able to do this because of the capabilities of the LTC1872, a constant frequency step-up DC/DC controller that comes in a SOT-23 package. The LTC1872 uses a current mode PWM architecture to drive an external N-channel power MOSFET in boost regulator applications

Key Features

    DC to DC
  • Input Voltage
    2.5 to 4.2 V
  • Output Voltage
    5 V
  • Output Current
    1 A
  • Topology
    Boost

Analog Devices LTM8052EV DEMO CIRCUIT 1866A

See the Analog Devices demo board DC1866 featuring the LTM8052, a 36-volt input step down micro module regulator with adjustable output voltage and output current limit. This means the LTM8052 will regulate either the user set output voltage or the output current, which can be a useful protection feature as this video demonstrates.
