Overview
The S-8338ABEB-P8T1G is a CMOS step-up switching regulator controller from the S-8338 series by ABLIC Inc. It operates within an input voltage range of 1.8V to 6V and supports a switching frequency between 257.4kHz and 1.134MHz. The device features a maximum duty cycle of 88.5% and functions as a positive output boost DC-DC controller. It utilizes pulse width modulation (PWM) control with current limit, enable, and frequency control characteristics. The component is housed in an 8-SON(A) package measuring 2.9x2.8mm and operates at temperatures from -40°C to 85°C.
Feature Summary
- Integrates a reference voltage circuit, oscillator, error amplifier, PWM controller, under voltage lockout, and timer latch short-circuit protection.
- Supports internal oscillation frequency setting up to 1.133 MHz via an external resistor connected to the ROSC pin.
- Designed for low-voltage operation starting at 1.8V, suitable for portable systems.
Applications
- Power supply for LCD displays
- Portable electronic systems operating on low voltage
Procurement Notes
Verify the specific suffix P8T1G against official datasheets to confirm the 8-SON(A) package type and lead-free status. Confirm RoHS compliance and REACH registration details prior to integration. Check for any Product Change Notifications regarding material or design updates that may affect compatibility.
Selection Notes
Select this component when a compact boost controller is required for low-voltage applications. Ensure the external inductor and capacitor values are compatible with the selectable frequency range. Verify that the load requirements do not exceed the controller's drive capabilities and that thermal management suits the 8-SON package constraints.
Part Context
This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The S-8338 variant specifically offers adjustable frequency settings compared to fixed-frequency counterparts. It is designed to replace older generation regulators in space-constrained portable devices requiring efficient power conversion.
Replacement Considerations
S-8338ABEA-P8T1G and S-8338ACCC-T8T1G are documented variants within the same series. Verify pin compatibility and electrical specifications before substitution.
