UPC1933 Product details

Description

The µ PC1933 is an IC that controls a low-voltage input DC-DC converter.

This IC is suitable for an operation with3-V, 3.3-V input or a lithium ion secondary battery input, because the minimum operating 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 output (1 cannel: This output can be used to control a step-down converter, a step-up converter. ).
Dead time is internally fixed to 85 %.
Soft start function (with a circuit to conver.
