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.
