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.
