The LTC3871, a 100V/30V bidirectional two phase synchronous buck or boost controller, ideal for 48V/12V automotive dual battery systems has been announced by Linear Technology. Current 12V automotive systems are reaching their 3kW power limit due to the ever-increasing demand for more electrical devices. A newly proposed standard, LV148, combines a secondary 48V bus with the existing 12V system.

  The LT3922 is a monolithic, synchronous, step-up DC/DC converter with internal 40V, 2A power switches and an internal PWM generator. Its fixed frequency peak current mode control accurately regulates current within ±2% for a string of LEDs up to 34V.

A new demonstration circuit, the 2459A, has been introduced by Linear Technology Corporation, and features the LTC1668, 50Msps and 16-bit digital-to-analogue converter (DAC). This DAC is well suited for applications with analogue frequency content between the audio range and several MHz.

Linear Technology Corporation introduces the LTM4650-1A and LTM4650-1B, dual 25A or single 50A µModule regulators scalable to deliver 300A to high power, low voltage sub-28nm GPUs, FPGAs, ASICs and microprocessors. The low core voltage of these digital devices requires very accurate voltage regulation at both steady state (DC) and fast load current transients.
