PC1933
DC-DC CONVERTER CONTROL IC
DESCRIPTION
The PC1933 is an IC that controls a low-voltage input DC-DC converter. This IC is suitable for an operation with3-V, 3.3-V input or a lithium ion secondary battery input, because the minimum operating supply voltage is 2.5 V. Because of its wide operating voltage range, it can also be used to control DC-DC converters that use an AC adapter for input.
FEATURES
Low supply voltage: 2.5 V (MIN.) Operating vol
