Description

  • Typical Application Circuit for LTC3838IUHF-1 3.3V to 14V Power Input, 1.2V/20A and 0.9V/20A Dual Output, 300kHz, RSENSE, Step-Down Converter with Externally-Available 5V to 5.5V Supply. The LTC3838-1 is a dual-channel, PolyPhase synchronous step-down DC/DC switching regulator controller. Two independent channels drive all N-channel power MOSFETs. The controlled on-time, valley current mode control architecture allows for not only fast response to transients without clock delay, but also constant frequency switching at steady load condition

This on-demand webinar will introduce you to the latest generation of Chip Embedded Power Modules from TDK, ideally for the future.

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.
