MT8102 2A, 30V, 450KHz Step-Down Converter DESCRIPTION The MT8102 is a monolithic step-down buck converter with a built-in internal switching power MOSFET. It generates 2A output current with fixed 450KHz switching frequency and a wide input supply range. Output voltage can be adjusted down to 0.8V. A voltage loop with inner current slope sensing PWM control provides fast transient response, ease loop stabilization and requires a very few external components. Protection features includes over current limiting and thermal shutdown. In shutdown mode the regulator only consumes less than 15uA current. MT8102 is available in a small MSOP-10L and SOP-8L and ESOP-8L Pb free package. PIN CONFIGURATION NC 1 10 NC BST 2 NC 3 VIN 4 MT8102MA (MSOP10) 9 EN 8 COMP 7 FB SW 5 6 GND FEATURES �� [ ... ]
