XCL102/XCL103 Series
ETR28011-005
Inductor Built-in Step-up “micro DC/DC” Converter (micro DC/DC)
☆Green Operation Compatible
■GENERAL DESCRIPTION
The XCL102/XCL103 series is a synchronous step-up micro DC/DC converter which integrates an inductor and a control IC in
one tiny package (2.0mm×2.5mm, h=1.0mm). A stable step-up power supply is configured using only two capacitors connected
externally. An internal coil simplifies the circuit and enables minimization of noise and other operational trouble due to the circuit
wiring. A wide operating voltage range of 0.65V to 6.0V enables support for applications that require an internally fixed output
voltage (2.2V to 5.5V). PWM control (XCL102) or automatic PWM/PFM switching control (XCL103) can be selected.
During the devices enter stand-by mode, XCL102D/XCL103D types prevent the application malfunction by CL Discharge
Function which can quickly discharge the electric charge at the output capacitor (CL). XCL102/XCL103E types is able to drive
Real Time Clock etc.

* Select components appropriate to the usage conditions (ambient temperature, input & output voltage).
While selecting a part, please concern about capacitance reduction and voltage durability.
(*1)
If VBAT≧2V, VOUT(T)≧3.5V and the load current rises above 200mA, use two or more in a parallel connection.
For the actual load capacitance, use a ceramic capacitor that ensures a capacitance equivalent to or greater than the TMK107BBJ106MA-T
(Taiyo Yuden).
If using tantalum or low ESR electrolytic capacitors please be aware that ripple voltage will be higher due to the larger ESR (Equivalent Series
Resistance) values of those types of capacitors. Please also note that the IC’s operation may become unstable with such capacitors so that
we recommend to test on the board before usage.

The error amplifier compares the internal
reference voltage with the resistors RFB1
and RFB2. Phase compensation is performed on the resulting error amplifier output, to input a signal to the PWM comparator to
determine the turn-on time of the N-channel driver transistor during PWM operation. The PWM comparator compares, in terms of
voltage level, the signal from the error amplifier with the ramp wave from the ramp wave circuit and delivers the resulting output
to the buffer driver circuit to cause the Lx pin to output a switching duty cycle. This process is continuously performed to ensure
stable output voltage.
The current feedback circuit monitors the N-channel driver transistor’s turn-on current for each switching operation and modulates
the error amplifier output signal to provide multiple feedback signals. This enables a stable feedback loop even when a low ESR
capacitor, such as a ceramic capacitor, is used, ensuring stable output voltage.
The reference voltage forms a reference that is used to stabilize the output voltage of the IC.
After “H” level is fed to CE pin, the reference voltage connected to the error amp increases linearly during the soft start interval.
This allows the voltage divided by the internal RFB1 and RFB2 resistors and the reference voltage to be controlled in a balanced
manner, and the output voltage rises in proportion to the rise in the reference voltage. This operation prevents rush input current
and enables the output voltage to rise smoothly.
The ramp wave circuit determines switching frequency. The frequency is fixed internally at 3.0MHz. The Clock generated is
used to produce ramp waveforms needed for PWM operation, and to synchronize all the internal circuits.
The error amplifier is designed to monitor output voltage. The amplifier compares the reference voltage with the feedback voltage
divided by the internal resistors (RFB1 and RFB2). When the FB is lower than the reference voltage, output voltage of the error
amplifier increases. The gain and frequency characteristics of the error amplifier are optimized internally.
VDD MAX circuit compares the input voltage and the output voltage then it will select the higher one as the power supply for the IC.
The IC enters chip disable state by applying low level voltage to the CE pin. At this time, the N-channel and P-channel
synchronous switching transistors are turned OFF
With the XCL102D/103D types, the orientation of the parasitic diode of the P-channel synchronous switching transistor is fixed
at anode: VOUT and cathode: Lx during shutdown to break conduction from the input side to the output side by the parasitic diode
of the P-channel synchronous switching transistor.
When PFM operates, the N-channel driver transistor turns on at the timing of the signal sent from the PWM comparator. The Nchannel driver transistor remains on until the current in the coil reaches a constant current (IPFM). The PWM/PFM control circuit
compares the signal sent from the PWM comparator to the time it takes the current in the coil to reach a constant current (IPFM),
and outputs the pulse that results in a longer on-time of the N-channel driver transistor. This enables smooth switching between
PWM and PFM. The XCL102 series directly outputs the signal that is sent from the PWM comparator.

XCL102/XCL103 Series
■OPERATIONAL EXPLANATION (Continued)
The maximum current limit function of XCL102D/E and XCL103D/E types monitors the current that flows in the Nch driver
transistor connected to the Lx pin and consists of both maximum current limiting and a latch function. (Fig.1)
Short-circuit protection (VSHORT) is a latch-stop function that activates when the output voltage drops below the short-circuit
protection threshold voltage in the overcurrent state. (Fig.2)
If the current flowing in the Nch (ILIM) driver transistor exceeds the current limit value (equivalent to the peak coil current), the
Nch driver transistor turns off, and remains off during the clock interval. In addition, an integral latch timer starts the count.
② The N-channel driver transistor turns on at the next pulse. If in the overcurrent state at this time, the Nch driver transistor
turns off as in (1). The integral latch timer continues the count.
③ If the count of the integral latch timer continues for 100μs (tLAT Typ.), a function that latches the Nch driver transistor and Pch
synchronous switching transistor to the off state activates.
④ If no longer in the overcurrent state at the next pulse, normal operation resumes. The integral latch timer stops the count.
