AT1730 Datasheet, PDF (1/7 Pages) List of Unclassifed Manufacturers – 2-Channel PWM Controller for LCD Bias

AT1730
Preliminary Product Information
2-Channel PWM Controller for LCD Bias
Features
• Low input voltage: 2.4V to 6V
• 2-Channels PWM Control:
Nch-MOSFET driving(CH1)
Nch/Pch-MOSFET driving(CH2)
• Adjustable Soft start time and maximum duty
cycle
• Built-in timer latch for short circuit protection:
• Built-in under-voltage lockout
• High operating frequency: 100kHz to 1.0MHz
• Low operating current: 2mA (typ.)
General Description
The AT1730 is a PWM DC/DC converter control
IC with 2 channel outputs that can directly drive
power MOSFET. This IC ia suitable for very small
DC/DC converters because of their small and thin
package(1.1 mm max.), and high operation
frequency (up to 1.0MHz).
Applications
• LCD Displays Bias
• Power Supply for general equipment
