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.
