High Voltage Isolated Monolithic Flyback Regulator Simplifies Design & Eliminates Optocoupler

High Voltage Isolated Monolithic Flyback Regulator Simplifies Design & Eliminates Optocoupler
Linear Technology announced the LT3512, a high voltage isolated monolithic flyback regulator that significantly simplifies the design of an isolated DC/DC converter. No optocoupler, third winding or signal transformer is required for feedback since the output voltage is sensed from the primary-side flyback signal. The LT3512 operates over a 4.5V to 100V input voltage range, has a 420mA, 150V power switch and delivers up to 4.5 watts of output power, making it well suited for a wide variety of telecom, datacom, automotive, industrial and medical applications.

36V with 60V Transient Protection, Dual Tracking 3.5A(IOUT), 2.25MHz Step-Down DC/DC Converter

Linear Technology has announced the LT3692, a monolithic, dual output step-down switching regulator that can deliver up to 3.5A of continuous output current from each channel. It operates from a VINrange of 3V to 36V with transient protection to 60V, making it ideal for load dump and cold-crank conditions found in automotive applications. Independent input, shutdown, feedback, soft-start, current limit and comparator pins for each channel simplify complex power supply tracking/sequencing requirements. The LT3692's switching frequency is user programmable from 250kHz to 2.25MHz, enabling the designer to optimize efficiency while avoiding critical noise-sensitive frequency bands.
