Low Voltage Operation STEP-UP DC/DC Converter
REJ03D0845-0300
Rev.3.00
Jun 15, 2007
Description
The M62216FP is designed as low voltage operation STEP-UP DC/DC converter.
This IC can operate very low input voltage (over 0.9 V) and low power dissipation. (circuit current is less than 850 µA)
So, this IC suitable for power supply of portable system that using low voltage battery. (DRY battery, rechargeable
battery)

Note:
VF: Forward voltage of external diode.
VCE (sat): Saturation voltage of external transistor.
VBE: Voltage between Base - Emitter of external transistor.
hFE: hFE of external transistor at saturating.
A1: Ratio of current into DRIVE1 terminal.
(A1 = 0.8~0.9)
A2: Ratio of current into DRIVE2 terminal.
(A2 = 1 − A1)
A3: Ratio of current into DRIVE2 terminal.
(A3 = 0.1~0.2)
• Set R2 to several kΩ ~ several 10ths kΩ.
• Set current into DRIVE2 terminal more than 100 µA.
(Ipk / hFE) × A2 ≥ 100 µA, (Ipk / hFE) × A3 ≥ 100 µA
• Set ∆IO to 1/5 ~ 1/3 of maximum load current
• The maximum rating of current of external parts (transistor,
diode and inductor) are 1.5 to 2 times of Ipk.
