EUP2410
1.6A, 500KHz Synchronous
Step-up Converter
DESCRIPTION
The EUP2410 is a highly efficient, synchronous, fixed
frequency, current-mode step-up converter with output to
input disconnect. When EUP2410 is disabled, the internal
conduction path from SW to OUT is fully blocked and the
OUT pin is isolated from the battery. This output disconnect
feature reduces the shutdown current to typically only 50nA.
The 500KHz switching frequency allows for smaller external
components producing a compact solution for a wide range
of load currents. Highly integration and internal
compensation network minimizes as 5 external components,
N-Channel switch and P-Channel Synchronous switch
integration will greatly improve converter efficiency.
Internal soft-start function also reduce inrush current. The
EUP2410 regulates the output voltage up to 6V from either a
2-cell NiMH/NiCd or a single-cell Li-Ion battery.
The EUP2410 is offered in a thin SOT23-5 package.

Pin Description
PIN NAME
1 FB
2 GND
3 OUT
4 SW
5 EN
DESCRIPTION
Regulation Feedback Input. Connect to an external resistive voltage divider from the
output to FB to set the output voltage.
Ground.
Supply Input for the EUP2410. Connect to the output of the converter.
Output Switching Node. SW is the drain of the internal low-side N-Channel MOSFET
and high-side P-Channel MOSFET. Connect the inductor to SW to complete the
step-up converter.
Regulator On/Off Control Input. A logic high input (VEN > 1.4V) turns on the
regulator. A logic low input (VEN < 0.4V) puts the EUP2410 into low current
shutdown mode.
