µ PC1935
DC-DC CONVERTER CONTROL IC
DESCRIPTION
The µ PC1935 is a low-
voltage input DC-DC converter control IC that can configure a three-output (step-up × 2, inverted output × 1) DC-DC converter at an input
voltage of 3, 3.
3, or 5 V.
Because of its wide operating
voltage range, this IC can also be used to control DC-DC converters using an AC adapter for input.
