XC9504 - Step-up / Inverting DC/DC Controller

General Description

The XC9504 series are PWM control, PWM/PFM switching, 2 channel (step-up and inverting) DC/DC controller ICs.

With 0.9V of standard voltage supply internal, and using externally connected components, the output 1 voltage (step-up DC/DC controller) can be set freely within a range of 1.5V ~ 30V.

Key Features

  • ch. DC/DC Controller (Step-Up + Inverting) Output Voltage Range : 1.5V ~ 30V (set by FB1 pin) Output Current : More than 20mA (VIN=3.3V, VOUT=15V) Soft-Start Internally Set-Up.
  • Portable audio systems.
  • Various multi-function power supplies Output Voltage Range : -30V ~ 0V (set by FB2 pin) Output Current : ≧-20mA (VIN=3.3V, VOUT=-7.0V) Supply Voltage Range : 2.0V ~ 10.0V Input Voltage Range.

XC9504 Series 2 ch. Step-Up / Inverting DC/DC Controller ICs ETR0704_002b ☆GreenOperation Compatible ■GENERAL DESCRIPTION The XC9504 series are PWM control, PWM/PFM switching, 2 channel (step-up and inverting) DC/DC controller ICs. With 0.9V of standard voltage supply internal, and using externally connected components, the output 1 voltage (step-up DC/DC controller) can be set freely within a range of 1.5V ~ 30V. Since output 2 (inverting DC/DC controller) has a built-in 0.9V reference voltage (accuracy ±2%), a negative voltage can be set with the external components. With a 180kHz frequency, the size of the external components can be reduced. Oscillation frequencies of 300kHz are also available as custom designed products.
