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. Switching frequencies of 300kHz and 500kHz
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 10msec (output 1)

Notes
1)
Although the IC's step-up operations start from a V DD of 0.8V, the output voltage and switching frequency are stabilized at VDD
≥ 2.0V. Therefore, a VDD of more than 2.0V is recommended when V DD is supplied from V IN or other power sources.
2)
Although the IC's switching operations start from a V IN of 0.9V, the IC's power supply pin (VDD) and output voltage monitor pin
(FB1) should be connected to VOUT1. With operations from V IN=0.9V, the 2nd channel's (output 2) EN2 pin should be set to
chip disable. Once ouput voltage VOUT1 is more than 2.0V, the EN2 pin should be set to chip enable.
3)
Please be careful not to exceed the breakdown voltage level of the peripheral parts.

XC9504 Series
2ch. Step-up / Inverting DC/DC Controller ICs
Operational Description
The XC9504 series are dual DC/DC (step-up + inverting) converter controller ICs with built-in high speed, low ON resistance buffers.
<Error Amp. 1>
Error Amplifier 1 is designed to monitor the output voltage and it compares the feedback voltage 1 (FB1) with the reference voltage Vref1.
In response to feedback of a voltage lower than the reference voltage Vref1, the output voltage of the error amp. decreases.
<Error Amp. 2>
Error Amplifier 2 is designed to monitor the output voltage and it compares the feedback voltage 2 (FB2) with the reference voltage Vref 2.
In response to feedback of a voltage lower than the reference voltage Vref2, the output voltage of the error amp. decreases.
<OSC Generator>
This circuit generates the internal reference clock.
<Ramp Wave Generator 1, 2>
The Ramp Wave Generator generates a saw-tooth waveform based on outputs from the OSC Generator.
<PWM Comparator 1, 2>
The PWM Comparator compares outputs from the Error Amp. and saw-tooth waveform. When the voltage from the Error Amp's output is
low, the external switch will be set to ON.
<PWM/PFM Controller 1, 2>
This circuit generates PFM pulses.
Control can be switched between PWM control and PWM/PFM automatic switching control using external signals.
The PFM/PWM automatic switching mode is selected when the voltage of the PWM1 (2) pin is less than 0.2V, and the control switches
between PWM and PFM automatically depending on the load. As the PFM circuit generates pulses based on outputs from the PWM
Comparator, shifting between modes occurs smoothly. PWM control mode is selected when the voltage of the PWM1 (2) pin is more than
0.65V. Noise is easily reduced with PWM control since the switching frequency is fixed.
Control suited to the application can easily be selected which is useful in audio applications, for example, where traditionally, efficiencies
have been sacrificed during stand-by as a result of using PWM control (due to the noise problems associated with the PFM mode in standby).
<Vref 1 with Soft Start 1>
The reference voltage, Vref1(FB1 pin voltage)=0.9V, is adjusted and fixed by laser trimming (for output voltage settings, please refer to the
functional settings notes on page 9.). To protect against inrush current, when the power is switched on, and also to protect against voltage
overshoot, soft-start time is set internally to 10ms. It should be noted, however, that this circuit does not protect the load capacitor (CL)
from inrush current. With the Vref voltage limited, and depending upon the input to error amp 1, the operation maintains a balance between
the two inputs of error amps and controls the EXT pin's ON time so that it doesn't increase more than is necessary.
<Vref 2>
The reference voltage, Vref2 (FB2 pin voltage)=0.9V, is adjusted and fixed by laser trimming.
<Enable Function 1,2>
This function controls the operation and shutdown of the IC. When the voltage of the EN1 or EN2 pins is 0.2V or less, the mode will
be disable, the channel's operations will stop and the EXT1 pin will be kept at a low level (the external N-type MOSFET will be OFF)
and the EXT2 pin will be kept at a high level (the external P-type MOSFET will be OFF). When both EN1 and EN2 are in a state of
chip disable, current consumption will be no more than 3.0µA.
When the EN1 or EN2 pin's voltage is 0.65V or more, the mode will be enable and operations will recommence. With channel one
(output 1) soft-start, 95% of the set output voltage will be reached within 10msec (TYP) from the moment of enable.

2ch. Step-up / Inverting DC/DC Controller ICs
Functional Settings
< Output Voltage Setting, Ch.1 (Step-up DC/DC Converter Controller) >
Output voltage can be set by adding external split resistors. Output voltage is determined by the following equation, based on the values of
RFB11 and RFB12. The sum of RFB11 and RFB12 should normally be 1 MΩ or less.
VOUT1=0.9 × (RFB11+RFB12) / RFB12
The speed-up capacitor for phase compensation's (CFB1) value should be adjusted using the formula fzfb=1/(2×π×CFB1×RFB11) so that it
equals 12kHz. Depending on the application, the inductance value L, and the load capacity value CL, adjustments to this value are
suggested so that the value is somewhere between 1kHz to 50kHz.
[Calculation Example]
When RFB11=470kΩ and RFB12=30kΩ : VOUT1=0.9 × (470k+30k) / 30k=15.0V.

< Output Voltage Setting, Ch.2 (Inverting DC/DC Converter) >
Output voltage can be set by adding reference voltage and split resistors externally. Output voltage is determined using the following
equation and is based on the values of RFB21 and RFB22. The sum of RFB21 and RFB22 should normally be 500kΩ or less. The
equation uses Ch 1's (VOUT1) output voltage calculation method for the reference voltage.
VOUT2 = (0.9 - VOUT1) x (RFB21 / RFB22) + 0.9V
[Calculation Example]
When RFB21=17.5kΩ, RFB22=10kΩ, VOUT1=3.3V, VOUT2= - 3.3V
The value of speed-up capacitor for phase compensation CFB21 :
[Conditions: Heavy load (when coil current is continous.)]
fzfb2 = 1/2 x π x CFB21 x RFB21) = 10kHz
Depending on the application, the inductance value L, and the load capacity value CL, adjustments to this value are suggested so that the
value is somewhere between 1kHz to 50kHz.
[Conditions: Light load (when coil current is discontinous.)]
Less than CFB21=0.1µF
Depending on the application, the inductance value L, and the load capacity value CL, adjustments to this value are suggested.

Hint on application
1. Channel 1 (step-up) How to shut down the output voltage during standby mode
If the circuit configuration shown as an example of typical application circuits is used, voltage VIN will occur at VOUT 1 when the IC is
in standby, the diode being bypassed. This can cause circuits connected to VOUT 1 to malfunction.

The combination of R 2, C 1, and the threshold
voltage of approximately 0.7 V of NPN Bip 1 is used
to produce a delay time between the circuits being
enabled and P-ch MOSFET 1 being switched on.
Delay time set to 20 mS ensures power to be made
ready in a favorable manner, as soft start of this
product is completed during the delay time.

Nch MOSFET 2 and the inverter enables power to be turned off quickly.
Soft start circuit
2. Channel 2 ( Inverting )
Channel 2 (inverting) is subject to the overshoot of output voltage 2 (VOUT 2) at start-up. It is possible to control the overshoot of
output voltage 2 (VOUT 2), as shown by circuit example 1 in “Output Voltage Settings for Channel 2” in “Function Settings.” In this
circuit configuration, EN 1 and EN 2 are enabled (set to “H” level) simultaneously. This lets output voltage 1 (VOUT 1) of channel 1
increase gently as soft start, thereby controlling the overshoot.
> Example of typical application circuit : Improved Soft start
This example is effective when EN 1 and EN 2 are enabled with different timings under light load condition (the coil current being
discontinuous).
Time to make soft start time is calculated by the equation below.

When VOUT1 = 15V and VOUT2 = - 7.5V,
RFB21 = 59.6kΩ, RFB22 = 100kΩ by the equation below.
VOUT2 = (0.9 - VOUT1) x (RFB21 / RFB22) + 0.9
When the light load, CFB21=0.1µF or lower value can be used.
Therefore, when CFB21=0.027µF,
Time_ss2 = 5.0mS and VOUT2 = 95% of setting value
3. Channel 2 (Inverting)
Withstand voltage of transistor
The voltage applied between the drain and source is the sum of VIN and VOUT 2.
Select a transistor with an absolute VDSS rating that is suitable for your operating conditions.
Example: The voltage applied across VDS of a transistor will be 20.0V if VIN = 5.0 V and VOUT 2 = -15.0 V.
Under this condition, a transistor with VDSS higher than 20.0V should be selected. (Use a transistor with VDSS
that is 1.5 times the applied voltage or more, as a standard.)

XC9504 Series
2ch. Step-up / Inverting DC/DC Controller ICs
Note on Use
1. PWM/PFM Automatic Switching
If PWM/PFM automatic switching control is selected and the step-up ratio is low (e.g., from 4.5 V to 5.0 V), the control mode
remains in PFM setting over the whole load range, since the duty ratio under continuous-duty condition is smaller than the PFM
duty ratio of the XC9504 series. The output voltage's ripple voltage becomes substantially high under heavy load conditions, with
the XC9504 series appearing to be producing an abnormal oscillation. If this operation becomes a concern, set pins PWM to
High to set the control mode to PWM setting. For use under the above-mentioned condition, measured data of PWM/PFM
automatic switching control shown on the data sheets are available up to IOUT = 100 mA.
2. Ratings
Use the XC9504 series and peripheral components within the limits of their ratings.
