AT1780 - Low-Noise Step-Up Current-Mode PWM Controller

General Description

The AT1780 is a current-mode step-up DC/DC converter with a 1.6A, 0.21Ω power MOSFET.

The soft-start function is programmed with an external capacitor, which sets the input current ramp rate.

It is ideal for generating bias voltages for LCD panels.

Key Features

  • 1.6A,0.21Ω,14V Power MOSFET.
  • Operating input voltage:+2.6V to +5.5V.
  • Adjustable Output from VIN to 12V.
  • 640kHz /1.2MHz pin selectable switching Frequency.
  • 0.1μA shutdown Current.
  • Built-in Soft-Start function.
  • Small 8-Pin MSOP Package General.
