42V, 3.5A (IOUT) Synchronous Step-Down Regulator with Operation to 175°C
2016-06-01 | ReturnThe LT8610AX utilizes internal top and bottom high efficiency power switches with the necessary boost diode, oscillator, control and logic circuitry integrated into a single die. This eliminates the need for any external Schottky diodes, which can be problematic at high temperatures. The LT8610AX’s lack of thermal shutdown is ideal for high temperature environments. Low ripple Burst Mode operation maintains high efficiency at low output currents while keeping output ripple below 10mVP-P. The LT8610AX’s current mode topology enables fast transient response and excellent loop stability. Specialized Cu/Ni/Au bond pad plating ensures long life in high temperature environments. Other features include internal compensation, a power good flag and output soft-start/tracking.
The LT8610AXMSE is packaged in a thermally enhanced MSOP-16 package, priced at $125.00 each in 1,000-piece quantities and available from stock. For more information, visit www.linear.com/product/LT8610AX.
