Overview
The S-8338ACDB-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 1.8 V to 6 V and supports a maximum oscillation frequency of 1.134 MHz. The device utilizes pulse width modulation (PWM) control with a maximum duty cycle of 88.5%. It is housed in an 8-SON package measuring 2.9x2.8 mm and functions within a temperature range of -40°C to 85°C.
Feature Summary
- Integrates under voltage lockout and timer latch short-circuit protection circuits for enhanced system reliability.
- Features a low minimum operating voltage suitable for portable systems powered by single-cell batteries.
- Allows external adjustment of the internal oscillation frequency via a resistor connected to the ROSC pin.
Applications
- Power supply units for liquid crystal displays (LCDs)
- Portable electronic devices requiring low-voltage operation
- Battery-powered consumer electronics
Procurement Notes
Verify the specific suffix ACDB against official datasheets to confirm package type and electrical characteristics, as variations exist within the S-8338 family. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure design compatibility with the 8-SON footprint and thermal requirements specified in the component datasheet.
Selection Notes
Select this component when a compact boost converter solution is required for low-voltage applications. The S-8338ACDB-P8T1G offers high-frequency operation to minimize external passive component size. Consider the 8-SON package constraints and verify that the required output voltage and current capabilities align with the controller's driver specifications.
Part Context
This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The series is designed for step-up applications where space efficiency and low input voltage performance are critical. The S-8338 variant typically shares core architecture with the S-8337 but may differ in specific control features or pin configurations.
Replacement Considerations
S-8338ABEA-P8T1G and S-8338ACDC-P8T1G are documented variants within the same series. Verify pin compatibility and specific electrical parameter differences before substitution.
