LвЂ‰DESIGN FEATURES Space-Saving, Dual Output
DC/DC Converter Yields Plus/Minus
Voltage Outputs with (Optional)
I2C Programming
by Mathew Wich
Introduction with on-chip OTP (One-Time-Programming) memory. The input supply range
is 2.55V to 5.5V and switch current
limits are 350mA and 600mA for the
boost and inverting switches, respectively. In addition, the LT3582 features
power up sequencing with ramping
from ground to regulation, power down
discharging, positive output disconnect and soft-start. There are many applications that require both positive and negative DC
voltages generated from a single input
supply. The LT3582 is a highly integrated dual switching regulator that
produces positive and negative voltages for AMOLEDs, CCDs, op amps, and
general В±5V and В±12V supplies. The
LT3582 uses a novel control scheme
resulting in low output voltage ripple
and high conversion efficiency over a
wide load current range. The total solution size is very small due to the tiny
3mm Г— 3mm 16-pin QFN package, integrated feedback resistors, integrated
loop compensation networks and the
single-inductor negative output topology (see FigureВ 1). …
