DESCRIPTION
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.
● 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 convert the timer latch circuit.)
