JW5213 3A, 6V, 1MHz, 50uA IQ Synchronous Step-Down Converter DESCRIPTION FEATURES ® The JW 5213 is a current mode monolithic buck  2.5V to 6V operating input range switching regulator. Operating with an input range  Up to 3A output current of 2.5V-6V, the JW5213 delivers 3A of continuous  Up to 95% peak efficiency output current with integrated P-Channel and  Internal soft-start N-Channel MOSFETs. The internal synchronous  1MHz switching frequency power switches provide high efficiency. At light  Input under voltage lockout loads, the regulator operate in low frequency to  Short circuit protection maintain high efficiency and low output ripples.  Over voltage protection Current mode control provides tight load transient  Thermal protection response and cycle-by-cycle current limit.  Hot-plug in protection The JW5213 guarantees robustness with latch off  Output POK indication output short-circuit protection, latch off  RoHS compliant and halogen free over-voltage protection, start-up current run-away  Available in DFN2X2-8 package protection, input under voltage lockout protection, 制 hot-plug in protection, and thermal protection.
