AT1729 Datasheet, PDF (1/8 Pages) List of Unclassifed Manufacturers – 3-Channel PWM Controller for LCD Bias

AT1729
Preliminary
3-Channel PWM Controller for LCD Bias
Features
• Low input voltage: 2.5V to 7V
• 3-Channels PWM Control:
2 Boost Controller(CH1,CH2)
1 Inverting Controller (CH3)
• Adjustable Soft start time and maximum duty
cycle
• Built-in timer latch for short circuit protection:
Delay time=216/(Switching frequency)
• Built-in under-voltage lockout, thermal
shutdown.
• High operating frequency: 100kHz to 1MHz
General Description
The AT1729 is a PWM DC/DC converter control
IC with 3 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 1.0 MHz).
Applications
• LCD Displays Bias
• Power Supply for general equipment
