HM1483 Datasheet | H&M Semiconductor

Features - 3.0A continuous output current capability - 6.5V to 30Vwide operating input range with input Over Voltage Protection - Integrated 36V, 65mΩ high side and 36V, 45mΩ low side power MOSFET switches - Up to 95% efficiency - Programmable Soft-Start limits the inrush current at turn-on - Stable with Low ESR Ceramic Output Capacitors - Fixed 300KHz Switching Frequency - Input Under-Voltage Lockout. - Input over-voltage protection to protect device from working in high voltage and high current condition - Output short protection with both high side current limit and low side current limit to protect the device in hard short - Output Over-Voltage Protection - Over-Temperature Protection - Small size Flip-Chip TSOT23-8 Package, best for narrow space application. More reliable and less parasitic voltage spike paring with bonding wire package 2 Applications - Set-Top-Box - Televisions - DVD, LCD Displays - OLPC, Netbook - Data, XDSL modems - Distributed Power Systems - USB car charger - Portable charging device - General purpose 3 Description HM1483 is a monolithic 30V, 3.0A step-down switch regulator. HM1483 integrates a 36V 65mΩ high side and a 36V, 45mΩ low side MOSFETs to provide 3.0A continuous load current over a 6.5V to 36V wide operating input voltage with 30V input over voltage protection. Peak current mode control provides fast transient responses and cycle-by-cycle current limiting. Programmable soft-start prevents inrush current at power-up. Flip-chip TSOT23-8 package makes the part best fit narrow space applications 4 Typical Application Schematic VIN/6.5V-30V C1 100u F/50V C2 0.1u F/50V 8 V2IN 2 8EN C5 100n F/25V SW3 7 +0 R4 4...
