KX-MB1520FX7/KX-MB1520FX8/KX-MB1520FXW/KX-MB1530FX7/KX-MB1530FXW

6.18.2. 3.3V and 1.2V Power Supply Descriptions (KX-MB1530 only)

1. IC800 is PWM type DC-DC converter controller, which make up step down type DC-DC converter circuit with Pch power

MOSFET Q802, coil of L801, schottky diode of D801, Capacitor of C808,C810 and C816,C817.
The oscillation frequency in operation of this DC-DC converter is set to about 300kHz.

2. IC801 is Low Dropout regulator and the output voltage is the fixed voltage 3.3V.
3. R812,R816,Q804 Q803 are Sequence circuit.(After 1.2V DC-DC converter is turned on, 3.3V(IC801)'s operation is turned on.)
4. R818,R814,Q805 Q803 are 24V Monitoring Circuit.

Q803 turns off when 24V output voltage is about 16V or less and CE terminal becomes low so that IC801's operation is
stopped.
