EUP2511
HQI
Boost Converter With 2.1A Switch
In Tiny SOT-23 Package
DESCRIPTION
The EUP2511 is a high performance current mode, PWM
step-up converter. With an internal 2.1A, 150m
MOSFET, it can generate 5V at up to 900mA output
current from a 3.6V supply. The fixed 600KHz operating
frequency allows small inductors and fast transient
response. The internal compensation structure will reduce
board size and the application cost. Integrated internal
soft-start also reduces inrush current during start-up.
The EUP2511 regulates the output voltage up to 6V from
either a 2-cell NiMH/NiCd or a single-cell Li-Ion battery.
The EUP2511 is offered in SOT23-5 package.
