UPC1934 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.

UPC1934 Key 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 inverte
