2 ch. Step-Up / Inverting DC/DC Controller ICs
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.
The control of the XC9504 series can be switched between PWM control and PWM/PFM automatic switching control using
external signals. Control switches from PWM to PFM during light loads when automatic switching is selected and the series
is highly efficient from light loads through to large output currents. Noise is easily reduced with PWM control since the
frequency is fixed.
The series gives freedom of control selection so that control suited to the application can be selected.
Soft-start time is internally set to 10ms (output 1) which offers protection against rush currents and voltage overshoot when
the power is switched on.
APPLICATIONS
Power supplies for LCD
PDAs
Palm top computers
Portable audio systems
Various multi-function power supplies
