Description of Blocks
ERROR AMPLIFER
This is an error amplifier using reference voltage of 0.6V (Typ) and “FB” terminal voltage as input. (Refer to p. 21 to p. 22
for phase compensation setting method). Duty width of switching pulse is controlled with “COMP” of error amplifier output.
Output voltage is set using “FB” terminal. Phase compensation can be adjusted by connecting capacitor and resistor to
“COMP” terminal.
SOFT START
This is a function for preventing overshoot of output voltage by gradually raising non-inverting input voltage of ERROR
AMPLIFIER to gradually increase duty of switching pulse at power on. Soft start can be set by connecting a capacitor
between “GND” terminals with “SS terminal”. (Refer to p. 22.)
OSCILLATOR
Oscillation frequency of 0.3 MHz to 2.4 MHz can be set by connecting a resistor between “RT” terminal and “GND”
terminal in the circuit which generates pulse waveform to be input to SLOPE. (Refer to Figure 18 on p. 21)OSCILLATOR
output sends clock signal to DRV. OSCILLATOR output is also used as the clock of SCP counter.
SLOPE
This is the block for generating saw-tooth wave from the clock formed by OSCILLATOR. Generated saw-tooth wave is
combined with feedback current of coil current and sent to PWM COMPARATOR.
PWM COMPARATOR
This is a comparator that compares SLOPE output and ERROR AMPLIFIER output.
DRV
This is a latch circuit having OSCILLATOR output (set) and PWM COMPARATOR output (reset) as input. It generates
PWM control signal and outputs gate signal for FET drive.

State enters test mode when EN terminal exceeds 6 V.
Within action power voltage range, the order of startup of power (VIN, PVIN), EN terminal and SEL terminal does not matter.
As an external signal, input frequency within ±25% of frequency set by RT resistance.
Output voltage is limited by SW minimum ON time depending on setting of input voltage and oscillation frequency. For the setting range, see setting
of output voltage of application part selection method (p. 20).
Ceramic capacitor is recommended. Set the capacitance value not to become below minimum value including variation, temperature property, DC
bias property and aging. Since malfunction may occur depending on substrate patterns and capacitor positions, please design the substrate
referring to cautions in substrate layout (p. 28).
