Product Description


2-Channel DC/DC Controllers

The X9505 is a dual channel Step-down + Inverter DC/DC controller IC. Output voltages are individually set-up externally, using two resistors and the control of the XC9505 series can be switched between PWM and PFM/PWM auto-switching using the MODE pin.

Control switches from PWM to PFM during light loads when auto-switching is selected. This maximises the efficiency across all output loads. In PWM mode noise is easily reduced since the switching frequency is fixed.

Features:

  • Input Voltage: 0.9V ~ 10.0V
  • Output Voltage Range:
    • Step-down: 0.9V ~ 6.0V
    • Inverting:    -30.0V ~ 0.0V
  • Switching Frequency: 180kHz, 300kHz or 500kHz 
  • Standby Current: 3.0μA (max)
  • Soft Start internally set-up
  • Output Voltage externally set-up
  • PWM, PWM/PFM switching control
