L DESIGN IDEAS 500mA Output Current Low Noise
by Yang Wen
Dual Mode Charge Pump
Introduction
Charge pump (inductorless) DC/DC
converters are popular in spaceconstrained applications with low to
moderate load current (10mAвЂ“500mA)
requirements. The devices in the
LTC3203 family are low noise, high
efп¬Ѓciency regulating charge pumps
that can supply up to 500mA of
output current from a single 2.7V
to 5.5V supply. The LTC3203-1 and
LTC3203B-1 produce a selectable п¬Ѓxed
4.5V or 5V output. The LTC3203B
produces an adjustable output voltage.
The LTC3203-1 features automatic
Burst Mode operation at light load to
achieve low supply current whereas
the LTC3203B and LTC3203B-1 operate at constant frequency to minimize
both input and output noise. High
switching frequency (1MHz) makes it
possible to use only four tiny low cost …
