S-8353/8354 Series www.ablic.com STEP-UP, PWM CONTROL or PWM / PFM SWITCHABLE BUILT-IN TRANSISTOR SWITCHING REGULATOR © ABLIC Inc., 2002-2020 Rev.3.1_00 The S-8353/8354 Series is a CMOS step-up switching regulator which mainly consists of a reference voltage source, an oscillation circuit, a power MOS FET, an error amplifier, a phase compensation circuit, a PWM control circuit (S-8353 Series) and a PWM / PFM switching control circuit (S-8354 Series). The S-8353/8354 Series can configure the step-up switching regulator with an external coil, capacitor, and diode. In addition to the above features, the small package and low current consumption make the S-8353/8354 Series ideal for portable equipment applications requiring high efficiency. The S-8353 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 models), an excellently designed error amplifier, and phase compensation circuits. The S-8354 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. (IOUT = 1 mA) guaranteed • Low current consumption : During operation 18.7 μA (3.3 V, 50 kHz, typ.) During shutdown: 0.5 μA (max.) • Duty ratio : Built-in PWM / PFM switching control circuit (S-8354 Series) 15 % to 83 % (30 kHz and 50 kHz models) 15 % to 78 % (250 kHz models) • External parts : Coil, capacitor, and diode • Output voltage : Selectable in 0.1 V steps between 1.5 V and 6.5 V (for VDD / VOUT separate types) Selectable in 0.1 V steps between 2.0 V and 6.5 V (for other than VDD / VOUT separate types) • Output voltage accuracy : ±2.4% • Oscillation frequency : 30 kHz, 50 kHz, and 250 kHz selectable • Soft start function : 6 ms (50 kHz, typ.) • Lead-free, Sn 100%, halogen-free*1 *1. Refer to “ Product Name Structure” for details.  Applications • Power supplies for portable equipment such as digital cameras, electronic notebooks, and PDAs • Power supplies for audio equipment such as portable CD / MD players • Constant voltage power supplies for cameras, VCRs, and communication devices • Power supplies for microcomputers  Packages • SOT-23-3 • SOT-23-5 • SOT-89-3 1 STEP-UP, PWM CONTROL or PWM / PFM SWITCHABLE BUILT-IN TRANSISTOR SWITCHING REGULATOR S-8353/8354 Series Rev.3.1_00  Block Diagrams (1) A, C and H Types (Without Shutdown Function) CONT VOUT Oscillation circuit PWMcontrol circuit or PWM / PFM swiching control circuit Soft start built-in reference power supply IC internal power supply + − Phase compensation circuit VSS Figure 1 (2) A and H Types (With Shutdown Function) CONT VOUT Oscillation circuit PWMcontrol circuit or PWM / PFM swiching control circuit Soft start built-in reference power supply IC internal power supply + − Phase compensation circuit VSS ON / OFF Figure 2 (3) D and J Types (VDD / VOUT Separate Type) CONT VDD VOUT Oscillation circuit IC internal power supply + PWMcontrol circuit − or PWM / PFM swiching control circuit Soft start built-in reference power supply Phase compensation circuit Figure 3 2 VSS STEP-UP, PWM CONTROL or PWM / PFM SWITCHABLE BUILT-IN TRANSISTOR SWITCHING REGULATOR Rev.3.1_00 S-8353/8354 Series  Product Name Structure The control system, product types, output voltage, and packages for the S-8353/8354 Series can be selected at the user’s request.
