STEP-UP, SUPER-SMALL PACKAGE, 600 kHz, PWM CONTROL or

PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER

Rev.7.0

_00

The S-8355/56/57/58 Series is a CMOS step-up switching regulator controller which mainly consists of a reference voltage

source, an oscillation circuit, an error amplifier, a phase compensation circuit, a PWM control circuit (S-8355/57 Series) and

a PWM/PFM switching control circuit (S-8356/58 Series).

With an external low-ON-resistance Nch Power MOS, this product is ideal for applications requiring high efficiency and a

high output current.

The S-8355/57 Series realizes low ripple, high efficiency, and excellent transient characteristics due to its PWM control

circuit whose duty ratio can be varied linearly from 0 to 83% (from 0 to 78% for 250 kHz, 300 kHz, and 600 kHz models), an

excellently designed error amplifier and a phase compensation circuits.

S-8356/58 Series features a PWM/PFM switching controller that can switch the operation to a PFM controller with a duty

ratio is 15% under a light load to prevent a decline in the efficiency due to the IC operating current.

Features

• Low voltage operation : Startup at 0.9 V min. (I

OUT

= 1 mA) guaranteed

• Low current consumption : During operation 25.9

μA

(3.3 V, 100 kHz, typ.)

During shutdown 0.5

• Duty ratio : Built-in PWM/PFM switching control circuit (S-8356/58 Series)

15 to 83% (100 kHz models)

15 to 78% (250 kHz, 300 kHz, and 600 kHz models)

• External parts : Coil, diode, capacitor, and transistor

• Output voltage : Selectable in 0.1 V steps between 1.5 and 6.5 V (for V
