MP2319GJ-Z

MPS MP2319 3A, 18V, 650kHz, High-Efficiency Synchronous Step-Down Converter Page 1 of 1 MP2319 3A, 18V, 650kHz, High-Efficiency, Synchronous, Step-Down Converter in 8-Pin TSOT23 DESCRIPTION FEATURES The MP2319 is a fully-integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. The MP2319 offers a very compact solution that achieves 3A of continuous output current with excellent load and line regulation over a wide input range. The MP2319 has synchronous mode operation for higher efficiency over the output current load range. Constant-on-time control operation provides a very fast transient response, easy loop design, and very tight output regulation. Full protection features include short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), over-voltage protection (OVP), and thermal shutdown. The MP2319 requires a minimal number of readily available, standard, external components and is available in a spacesaving, 8-pin, TSOT23 package. • • • • • • • • • • • • • Wide 4.5V to 18V Operating Input Range 3A Output Current 105mΩ/57mΩ Low RDS(ON) Internal Power MOSFETs Output Adjustable from 0.8V EN Shutdown Output Discharge Internal Soft Start High-Efficiency Synchronous Mode Operation Fixed 650kHz Switching Frequency EN and Power Good for Power Sequencing Over-Current Protection (OCP) and Hiccup Thermal Shutdown Auto-Retry Over-Voltage Protection (OVP) Available in a TSOT23-8 Package APPLICATIONS • • • • • Security Cameras Portable Devices, xDSL Devices Digital Set-Top Boxes Flat-Panel Televisions and Monitors General Purposes All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
