General Description
The EC9210 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 EC9210 includes under-voltage lockout, current limit, and over-temperature shutdown preventing damage in the event of an output overload.
