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, suited for various automotive, industrial, medical and military applications. The LT8304-1 version is tailored for high-output voltages up to 1 kV.
These devices operate in boundary mode, which is a variable frequency current mode control switching scheme, typically resulting in better than ±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. 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, internal soft-start and loop compensation, along with output diode temperature compensation.
The LT8304H/-1 operates over a –40° C to 150° C junction temperature range and is available in a small thermally enhanced SO-8 package. Pricing starts at $3.55 each in 1,000-piece quantities.
