STEP-UP, PWM CONTROL or PWM / PFM SWITCHABLE BUILT-IN TRANSISTOR SWITCHING REGULATOR
Rev.3.0_01
S-8353/8354 Series
External parts
Coil:
CDRH6D28-101 of Sumida Corporation
Diode:
MA2Z748 (Shottky type) of Matsushita Electric Industrial Co., Ltd.
Capacitor: F93 (16 V, 22 μF tantalum type) of Nichicon Corporation
VIN = VOUT(S) × 0.6 applied, IOUT = VOUT(S) / 250 Ω
With shutdown function :
ON / OFF pin is connected to VOUT
For VDD / VOUT separate type : VDD pin is connected to VOUT pin
Remark
1. VOUT(S) specified above is the set output voltage value, and VOUT is the typical value of the actual output
voltage.
2. VDD / VOUT separate type
A step-up operation is performed from VDD = 0.8 V. However, 1.8 V≤VDD≤10 V is recommended stabilizing
the output voltage and oscillation frequency. (VDD≥1.8 V must be applied for products with a set value of less
than 1.9 V.)
