MP1655 Datasheet | Monolithic Power Systems

5A, 17V, 600k Hz Synchronous, COT Step-Down Converter in 2x2mm QFN DESCRIPTION Features The MP1655 is a fully integrated, high- - Wide 4.2V to 17V Operating Input Range frequency, synchronous, rectified, step-down, - 59mΩ/27mΩ Low RDS(ON) Internal Power switch-mode converter with internal power MOSFETs MOSFETs. The MP1655 offers a very pact solution that achieves 5A of continuous output - 210μA Low IQ Current - High-Efficiency Synchronous Mode current with excellent load and line regulation Operation over a wide input range. The MP1655 uses synchronous mode operation for higher ly efficiency over the output current load range. n Constant-on-time (COT) control operation provides very fast transient response, easy loop O design, and very tight output regulation. e Full protection Features include short-circuit s protection (SCP), over-current protection (OCP), U under-voltage protection (UVP), and thermal shutdown. Y The MP1655 requires a minimal number of R readily available, standard, external ponents and is available in a space-saving A 6-pin QFN (2mmx2mm) package.
