a
Setting Output Voltage(VOUT):
Stepwise setting with a step of 0.1V in the range of 1.2V to 6.0V is possible.
Adjustable type; a=10 means Reference voltage=1.0V Optional Function is G/H/M.
b
Designation of Oscillator Frequency
2 : fixed
c
Designation of Optional Function
E : 300kHz, with a PWM/VFM alternative circuit
F : 500kHz, with a PWM/VFM alternative circuit
G : 300kHz, without a PWM/VFM alternative circuit
H : 500kHz, without a PWM/VFM alternative circuit
L : 180kHz, with a PWM/VFM alternative circuit
