Buck-Boost Regulator
SiP1759
Vishay Siliconix
DESCRIPTION
The SiP1759 is a buck-boost regulating charge pump. It is
designed to provide a regulated output from 1 cell Li Ion or 2/
3 cell NiMH voltages found in handheld portable equipment,
1.6 V to 5.5 V. SiP1759 allows the option of a fixed 3.3 V
output voltage, or an adjustable output which can be set from
2.5 V to 5.5 V. The output current is up to 100 mA.
For flexibility in application, SiP1759 has a shutdown pin
(SD) and an ERROR output to indicate when the output
voltage is in regulation.
SiP1759 is available in a 10 pin MSOP package and is rated
over the industrial temperature range of - 40 °C to 85 °C.
