A synchronous step-down DC/DC converter from Linear Technology Corp. is designed to regulate output current up to 20A.
Linear Technology (Milpitas, Calif.) said the converter's 6V to 36V input voltage range, constant current and constant voltage operation makes it suited for applications ranging from battery and supercap chargers and laser drivers to high current LED lighting.
The LT3741 converter uses two external switching MOSFETs and is said to deliver up to 20A of continuous output current over a wide voltage range of 0V to 34V. Efficiencies as high as 95 percent eliminate the need for an external heat sink.
Linear said the LT3741's frequency can be programmed and synchronized between 200 KHz and 1 MHz, allowing designers to optimize efficiency while minimizing external component size.
Extended temperature versions, or "I" Grades, the LT3741IUF and LT3741IFE, are also available. Pricing starts at $4.65 and $4.82 each, respectively in 1,000-piece quantities. All versions are available from stock.
