Data Sheet No. PD94703 revA
IRU3065(PbF)
POSITIVE TO NEGATIVE DC TO DC CONTROLLER
PRODUCT DATASHEET
FEATURES
Generate Negative Output from +5V Input
1A Maximum Output Current
1.5MHz maximum Switching Frequency
Few External Components
Available in 6-Pin SOT-23
DESCRIPTION
The IRU3065 controller is designed to provide solutions
for the applications requiring low power on board switch-
ing regulators. The IRU3065 is specifically designed
for positive to negative conversion and uses few com-
ponents for a simple solution. The IRU3065 operates at
high switching frequency (up to 1.5MHz), resulting in
smaller magnetics. The output voltage can be set by
using an external resistor divider. The stability over all
conditions is inherent with this architecture without any
compensation. The device is available in the standard
6-Pin SOT-23.
