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.
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 %.
