UPC1935 - DC-DC CONVERTER CONTROL IC

General Description

The µ PC1935 is a low-voltage input DC-DC converter control IC that can configure a three-output (step-up × 2, inverted output × 1) DC-DC converter at an input voltage of 3, 3.3, or 5 V.

Key Features

  • Low supply voltage: 2.5 V (MIN. ).
  • Operating voltage range: 2.5 to 20 V (breakdown voltage: 30 V).
  • Can control three output channels.
  • Timer latch circuit for short-circuit protection.
  • Ceramic capacitor with low capacitance (0.1 µ F) can be used for short-circuit protection.
  • Dead times of channels 2 (step-up) and 3 (inverted output) can be set from external resistors. Dead time of channel 1 (step-up) is internally fixed to 85 %.
  • S.

DATA SHEET BiCMOS INTEGRATED CIRCUIT µ PC1935 DC-DC CONVERTER CONTROL IC DESCRIPTION The µ PC1935 is a low-voltage input DC-DC converter control IC that can configure a three-output (step-up × 2, inverted output × 1) DC-DC converter at an input voltage of 3, 3.3, or 5 V. Because of its wide operating voltage range, this IC can also be used to control DC-DC converters using 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) • Can control three output channels. • Timer latch circuit for short-circuit protection. • Ceramic capacitor with low capacitance (0.1 µ F) can be used for short-circuit protection. • Dead times of channels 2 (step-up) and 3 (inverted output) can be set from external resistors.
