com 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 ...
