XC9133 Series
■ OPERATIONAL EXPLANATIONS (Continued)
<Current Limit>
The current limit circuit of the XC9133 series monitors the current flowing through the N-channel MOS driver transistor
connected to the Lx pin, and features a combination of the constant-current type current limit mode and the duty cycle limit
of the next pulse.
1 When the driver current is greater than a specific levels, the constant-current type current limit function operates to
turn off the pulses from the Lx pin at any given timing.
2 The IC controls the next pulse to be smaller than the first pulse.

reached the value of the constant current limit.
<Lx Overvoltage Limit Circuit>
XC9133 series' Lx overvoltage limit circuit monitors the Lx pin voltage. When the Lx pin voltage exceeds than 19V (TYP.),
the IC performs the function of latching the OFF state of the driver transistor, and goes into operation suspension mode.
In suspension mode, operations can be resumed by restoring power to the V IN pin. The suspension mode does not mean
a complete shutdown, but a state in which pulse output is suspended; therefore, the internal circuitry remains in operation.
<Maximum Duty Cycle Limit>
The XC9133 series' maximum duty cycle limit circuit monitors the duty cycle. When the maximum duty cycle is repeated
for a certain time, the IC controls the error amplifier output so that the duty cycle of the next pulse becomes smaller than
that of the first pulse.
<CE Pin Function>
The operation of the XC9133 series will enter into the shut down mode when a low level signal is input to the CE pin.
During the shut down mode, the supply current is 0 μ A (TYP.), with high impedance at the Lx pin. The IC starts its
operation with a high level signal to the CE pin. The input to the CE/MODE pin is a CMOS input and the sink current is 0
μ A (TYP.). 100 μ s after disable, the IC goes into suspension mode and supply current is minimal. After this, the IC will
be in stand-by mode and the supply current will be 0 μ A (TYP.).
