com AT1731 Preliminary 2-Channel PWM Controller for LCD Bias General Description The AT1731 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.
0 MHz).
Features • Low input voltage: 2.
5V to 7V • 2-Channels PWM Control: 1 Boost Controller(CH1) 1 Inverting Controller (CH2) • 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...
