JW5255A 5A, 5.5V, 1MHz, 60uA IQ Synchronous Step-Down Converter DESCRIPTION The JW®5255A is a monolithic buck switching regulator based on constant on-time (COT) control for fast transient response. Operating with an input range of 2.5V-5.5V, the JW5255A delivers 5A of continuous output current with integrated P-Channel and N-Channel MOSFETs. The internal synchronous power switches provide high efficiency. At light loads, the regulator operates in low frequency to maintain high efficiency. The JW5255A guarantees robustness with hiccup output short-circuit protection, FB short-circuit protection, start-up current run-away protection, input under voltage lockout and thermal protection.
