The LT3692A is a monolithic, dual 3A input/output buck converter with a 3V–36V operating range. The two channels are completely independent and can have different input voltages, output voltages, current limits, power good outputs, soft-start, undervoltage lockouts and even different synchronized switching frequencies.
The LT3692A is a monolithic dual 3A step-down converter designed to simplify DC/DC conversion in automotive, industrial, and distributed power systems. It features a wide input voltage range from 3V to 36V and includes overvoltage transient protection up to 60V. The device offers flexible configuration options, allowing designers to power it from one or two separate inputs while producing two independent outputs or parallelized high-current supplies.
Key design features include completely independent channels with programmable undervoltage lockout (UVLO) and overvoltage lockout (OVLO). The converter supports adjustable switching frequencies between 250kHz and 2.25MHz, which can be synchronized across multiple regulators via a clock output pin. Additional protections include soft-start to eliminate input current surges, internal thermal shutdown, and programmable power good outputs for system sequencing.
The device operates with an input voltage ranging from 3V to 36V.
