Description

  • PMP4937, 8VDC-16VDC 7.6V/700mA LED Driver. Reference design drives two series connected white LEDs at 700mA. The steady-state input range is 8VDC to 16VDC, but the circuit is designed to survive a 52VDC input transient condition. The TPS40211 boost controller is used in an "upside-down" buck topology for a simple, low-cost solution. This circuit includes enable, PWM dimming, current trimming, and a current sense functions for interfacing with an external Microprocessor

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.
