The LT8304 operates over a 3 V to 100 V input voltage range, has a 2 A/150 V integrated DMOS power switch, and delivers up to 24 W of output power, suiting it for a wide variety of telecom, datacom, automotive, industrial, medical and military applications.
The LT8304 operates in boundary mode, which is a variable-frequency current-mode control switching scheme, typically resulting in ±5% output voltage regulation over the full line, load and temperature range. Boundary mode enables the use of a smaller transformer compared to equivalent continuous conduction-mode designs. The output voltage is easily set by two external resistors and the transformer turns ratio. Several off-the-shelf transformers, identified in the data sheet, can be used for numerous applications. The high level of integration and the use of low-ripple Burst Mode® operation result in a simple-to-use, low-component-count and high- efficiency solution for isolated power delivery.
Additional features include output short-circuit protection, 116 µA no-load operating quiescent current, accurate enable and undervoltage lockout with hysteresis, and internal soft start and loop compensation, along with output diode temperature compensation.
The LT8304 is available in a small, thermally enhanced SO-8 package. Extended and industrial versions operate over a junction temperature range of -40° C to 125° C. Pricing starts at $3.55 each in 1,000-piece quantities.
