DESCRIPTION
The
µ PC1934 is an IC that controls a low-voltage input DC-DC converter. This IC is suitable for an operation with 3-V,
3.3-V input or a lithium ion secondary battery input, because the minimum operation 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 voltage range: 2.5 to 20 V (breakdown voltage: 30 V)
• Timer latch circuit for short-circuit protection.
• Ceramic capacitor with low capacitance (0.1
µ F) can be used for short-circuit protection.
• Open drain outputs (Each of the outputs can be used to control a step-down converter, a step-up converter and an
inverted converter.)
• Can control two output channels.
