High Efficiency 1.5MHz, Step up Regulator
EC9211
General Description
Features
The EC9211 is a fixed switching frequency (1.5MHz typical),
current-mode, step-up regulator with an integrated N-channel
MOSFET. The device allows the usage of small inductors and
output capacitors for portable devices. The current-mode control
scheme provides fast transient response and good output voltage
accuracy.
The EC9211 includes under-voltage lockout, current limit, and
over-temperature shutdown preventing damage in the event of an
output overload.
