Description

  • DC378A, Demonstration Board using LTC1778 high efficiency synchronous step-down buck regulator. The controller uses a valley current control architecture to deliver very low duty cycles without requiring a sense resistor. It provides high efficiency operation at light loads by means of discontinuous mode operation. Noise and RF interference are reduced by a forced continuous control pin. With a wide operating range of VIN = 4V to 36V and duty cycles of 2% to 90% at 200kHz, the LTC1778 is ideal for the applications such as notebook and palmtop computers, PDAs, battery chargers and distributed power systems

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.
