TOREX XC9504

XC9504 Series
ETR0704_001
2 ch. Step-Up / Inverting DC/DC Controller ICs
☆Green Operation 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.
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.

■ELECTRICAL CHARACTERISTICS (Continued)
NOTE:
*1 Although the IC's step-up switching operations start from a VDD of 0.8V, the output voltage and oscillation frequency are
stabilized at VDD ≧2.0V. Therefore, a VDD of more than 2.0V is recommended when VDD is supplied from VIN or other
power sources.
*2 Although the IC's operations start from a VIN of 0.9V, the IC's power supply pin (VDD) and output voltage monitor pin (FB1)
should be connected to VOUT1. With operations from VIN=0.9V, the 2nd channel's (output 2) EN2 pin should be disabled.
Once output voltage VOUT1 is more than 2.0V, the EN2 pin should be enabled.
*3 Please be careful not to exceed the breakdown voltage level of the peripheral parts.

XC9504 Series
■OPERATIONAL EXPLANATION
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 voltage1 (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 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 PWM/PFM 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 oscillation 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 stand-by).
<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 below.). 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-ch
MOSFET will be OFF) and the EXT2 pin will be kept at a high level (the external P-ch 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.

■OPERATIONAL EXPLANATION (Continued)
< 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 200kΩ
or less. The equation uses Ch 1's (VOUT1) output voltage calculation method for the reference voltage.
VOUT2 = (0.9-VOUT1) × (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 continuous.)]
fzfb2 = 1/2 ×π×CFB21×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 discontinuous.)]
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.

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 VOUT1 when
the IC is in standby, the diode being bypassed. This can cause circuits connected to VOUT1 to malfunction.

Set R1 so as to prevent leakage current of NPN (Bip 1).
N-ch MOSFET 2 and the inverter enables power to be turned off quickly.
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 20ms
ensures power to be made ready in a favorable
manner, as soft start of this product is
completed during the delay time.

2. Channel 2 (Inverting): Soft start circuit
Channel 2 (inverting) is subject to the overshoot of output voltage 2 (VOUT2) at start-up. It is possible to control the
overshoot of output voltage 2 (VOUT2), 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 (VOUT1) 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).

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 VOUT2. 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 VOUT2 = -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.)

■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.
