XCL213/XCL214 Series
ETR28005-001a
1.5A Inductor Built-in Step-Down “micro DC/DC” Converters
GENERAL DESCRIPTION
GreenOperationCompatible
The XCL213/XCL214 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC
in one tiny package (2.5mm×3.2mm, h=1.0mm). 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 2.7V to 5.5V enables support for
applications that require an internally fixed output voltage (0.8V to 3.6V). The XCL213/XCL214 series uses synchronous
rectification at an operating frequency of 3.0MHz. The XCL213/XCL214 series uses HiSAT-COT (*) synchronous rectification.
HiSAT-COT+PWM control (XCL213) or HiSAT-COT+automatic PWM/PFM switching control (XCL214) can be selected.
The series have a high speed soft-start as fast as 0.3ms in typical for quick turn-on. With the built-in UVLO (Under Voltage Lock
Out) function, the internal P-channel driver transistor is forced OFF when input voltage becomes 2.0V or lower. When
CE=Low, the integrated CL discharge function which enables the electric charge at the output capacitor CL to be discharged via
the internal discharge switch located between the LX and VSS pins. The power consumption will be less than 1.0μA.
(*) HiSAT-COT is an original Torex term for High Speed Transient Response.

XCL213/XCL214
Series
OPERATIONAL EXPLANATION
The XCL213/XCL214 series consists of a reference voltage source, error amplifier, comparator, phase compensation, minimum
on time generation circuit, output voltage adjustment resistors, P-channel MOS driver transistor, N-channel MOS switching
transistor for the synchronous switch, current limiter circuit, UVLO circuit, thermal shutdown circuit, short protection circuit,
PWM/PFM selection circuit and others. (See the BLOCK DIAGRAM below.)
<BLOCK DIAGRAM>
The method is HiSAT-COT (High Speed circuit Architecture for Transient with Constant On Time) control, which features on
time control method and a fast transient response that also achieves low output voltage ripple.
The on time (ton) is determined by the input voltage and output voltage, and turns on the Pch MOS driver Tr. for a fixed time.
During the off time (toff), the voltage that is fed back through R1 and R2 is compared to the reference voltage by the error amp,
and the error amp output is phase compensated and sent to the comparator. The comparator compares this signal to the
reference voltage, and if the signal is lower than the reference voltage, sets the SR latch. On time then resumes. By doing this,
PWM operation takes place with the off time controlled to the optimum duty ratio and the output voltage is stabilized. The phase
compensation circuit optimizes the frequency characteristics of the error amp, and generates a ramp wave similar to the ripple
voltage that occurs in the output to modulate the output signal of the error amp. This enables a stable feedback system to be
obtained even when a low ESR capacitor such as a ceramic capacitor is used, and a fast transient response and stabilization of
the output voltage are achieved.
<Minimum on time generation circuit>
Generates an on time that depends on the input voltage and output voltage (ton). The on time is set as given by the equations below.
ton (ns) = VOUT/VIN×333
<Switching frequency>
The switching frequency can be obtained from the on time (ton), which is determined by the input voltage and output voltage,
as given by the equation below.
fOSC (MHz) = VOUT(V) / (VIN(V)×ton(ns))
<100% duty cycle mode>
When the load current is heavy and the voltage difference between input voltage and output voltage is small, 100% duty cycle
mode is activated and it keeps the Pch MOS driver Tr. turning on. 100% duty cycle mode attains a high output voltage stability
and a high-speed response under all load conditions, from light to heavy, even in conditions where the dropout voltage is low.
<Error amp>
The error amp monitors the output voltage. The voltage divided by the internal R1 and R2 resistors is a feedback voltage for
Error Amp. and compared to the reference voltage. The output voltage of the error amp becomes higher when the feedback
voltage is higher than the reference voltage. The frequency characteristics of the error amp are optimized internally.
