AT1729 Datasheet | Unknown Manufacturer

Preliminary 3-Channel PWM Controller for LCD Bias 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). 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...
