UPC1934 - DC-DC CONVERTER CONTROL IC

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.

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.

DATA SHEET BiCMOS INTEGRATED CIRCUIT µ PC1934 DC-DC CONVERTER CONTROL IC 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.
