Equivalent circuit
1
BOOT
Upper MOS transistor boot strap capacitance connection pin.
No.A1762-4/5
Connect the boot capacitance of about 0.01
μF between SW
pins.
To protect the SW pin’s absolute maximum rating, to ensure
stable operation, and to eliminate noise, the boot capacitance
serial resistance (about 100
Ω) Rb proves effective.
2
VIN
Input voltage pin.
Connect substantially large (20
μF or more) capacitance
between this pin and GND.
VIN
CBOOT
SW
Hi side MOS
Low side MOS
3
SW
Power switch pin.
Connect the output LC filter. Connect the above capacitance
between this pin and BOOT pin.
4
GND
Ground pin.
5
FB
Feedback pin.
Sets the output voltage by means of split resistor in the section
of the output voltage VOUT - FB - GND. VOUT setting is made
as calculated below:
VOUT = Vref × { 1 +
(R1 + R10)
R3
}
Vref = 0.8V
Example: 3.3V output voltage
(See Block Diagram and Sample Application Circuit)
VOUT = 0.8 × { 1 +
(27k + 4.3k)
10k
}
=3.304V

SS
Soft start pin.
Sets the soft start time by means of the built-in 10
μA source
voltage and external soft start capacity. The soft start capacity
C6 can be set as follows:
C6 = 10
μA ×
Tss
Vref
Where, Tss is the soft start time and Vref is the reference
voltage.
Example: 1.2ms soft start time achieved
C6 = 10

1.2ms
0.8 V = 0.015μF
6
COMP
Phase compensation pin.
COMP
VIN
Internal regulation line
Clump circuit
Connects with the phase compensation external capacitance
and resistance of DC/DC converter close loop.
7
EN
Enable pin.
EN
VIN
2pF
Q117
Converter enabled when set to the HIGH voltage and disabled
when LOW voltage or OPEN state.
