Overview
The S-8338ACAB-P8T1G is a CMOS step-up switching regulator controller from the S-8338 series by ABLIC Inc. It operates with a minimum input voltage of 1.8 V and supports an internal oscillation frequency up to 1.133 MHz via an external resistor on the ROSC pin. The device features pulse width modulation (PWM) control, an under-voltage lockout circuit, and timer latch short-circuit protection. It is housed in an 8-SON(A) package measuring 2.9x2.8 mm and functions within a temperature range of -40°C to 85°C.
Feature Summary
- Supports low-voltage operation starting at 1.8 V for portable applications
- Features adjustable internal oscillation frequency up to 1.133 MHz
- Includes built-in under-voltage lockout and short-circuit protection circuits
Applications
- Power supply for LCD modules
- Portable electronic systems operating on low voltage
- Step-up DC-DC converter designs requiring compact footprint
Procurement Notes
Verify the specific suffix 'P8' corresponds to the 8-SON(A) package configuration as documented in official datasheets. Confirm that the ACAB variant aligns with the required electrical characteristics and thermal performance for the target application environment before finalizing procurement orders.
Selection Notes
Select this component when designing boost converters requiring high-frequency operation and minimal input voltage. Ensure external components support the selected switching frequency and current requirements. Verify compatibility with the 8-SON(A) package dimensions for PCB layout constraints.
Part Context
This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. These devices are designed for efficient power management in battery-powered systems, offering integrated protection features and flexible frequency adjustment through external resistors.
Replacement Considerations
S-8338AADB-P8T1G and S-8338ABEA-P8T1G are confirmed substitutes within the same series offering identical functional specifications and package types.
