AIC3414
1.2MHz, Synchronous Step-Up Converter in SOT23-6
„ FEATURES
„ DESCRIPTION
z Output Voltage Range: 2.5V to 4.0V
z Synchronous 92% Efficient Boost Converter
z 1.2 MHz Fixed Switching Frequency
z Built-in current mode compensation
z Built-in Protection: Over Current Protection and
Over Temperature Protection.
z Quiescent Current:300μA at VIN=1.1V, VOUT=3.3V,
IOUT=0A
z <1μA Shutdown Standby Current
z EMI Reduction Anti-Ringing Control Circuitry
z Thin SOT23-6 package
The AIC3414 step-up converter is based on a fixed
frequency, pulse-width-modulation (PWM) controller
using an internal synchronous rectifier to obtain
maximum efficiency. It stays in operation with supply
voltages down to 0.5V. The AIC3414 provides a
complete power supply solution for products po-
wered by either one or two Alkaline, Ni-Cd, or Ni-MH
battery cells. The AIC3414 output voltage can be
adjustable up to 4.0V. At light load condition, the
AIC3414 can work at PSM mode to improve effi-
ciency and reduce quiescent current.
„ APPLICATIONS
z Single / Dual Cells Ni-Cd / Ni-Mh Type Battery
Operated Products
z Internet Audio Player
z Wireless and DSL Modems
z Digital Still Cameras
z Portable Equipment
The AIC3414 includes the anti-ringing circuitry. The
anti-ringing circuitry is implemented to reduce ringing
and in effect lower radiated electromagnetic energy
when the converter enters the discontinuous con-
duction mode.
