Accepting an input ranging from 3.7V to 42V, the part is said to be suited to high temperature applications such as down hole drilling equipment.
The LT8610AX features internal top and bottom high efficiency power switches with the necessary boost diode, oscillator, control and logic circuitry integrated into a single die. This is said to eliminate the need for external Schottky diodes. Meanwhile, the lack of thermal shutdown is claimed as ideal for high temperature environments.
The LT8610AX’s current mode topology enables fast transient response and high loop stability. With specialised Cu/Ni/Au bond pad plating providing long life in high temperature environments, other features include internal compensation, a power good flag and output soft-start/tracking.
At ambient temperatures of 175°C, the LT8610AX offers more than 90% efficiency for 12V in to 3.3V out conversions over a load current range from 10mA to 1A.
