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 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 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.

This circuit generates the internal reference clock.

The ramp wave generator generates a saw-tooth waveform based on outputs from the OSC generator.

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.

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).

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.

The reference voltage, Vref2 (FB2 pin voltage)=0.9V, is adjusted and fixed by laser trimming.

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.

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).

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.
