Overview
The S-8337ACBB-P8T1G is a CMOS step-up switching regulator controller from the S-8337 series, manufactured by ABLIC Inc. It operates within a supply voltage range of 1.8 V to 6 V and utilizes pulse width modulation (PWM) control. The device features an internal oscillator with a frequency settable up to 1.134 MHz via an external resistor. It is housed in an 8-SON package measuring 2.9 x 2.8 mm and supports operation temperatures from -40°C to 85°C.
Feature Summary
- Integrates a reference voltage circuit, error amplifier, and PWM controller for efficient step-up regulation.
- Includes under-voltage lockout and timer latch short-circuit protection circuits for enhanced reliability.
- Allows adjustable maximum duty ratio through an external resistor connected to the RDuty pin.
Applications
- Power supply for LCD panels
- Portable electronic systems operating on low voltage
- Battery-powered devices requiring step-up conversion
Procurement Notes
Verify the specific suffix P8T1G corresponds to the 8-SON package configuration rather than TSSOP variants. Confirm RoHS compliance status and REACH registration details against current manufacturer documentation. Ensure ordering quantities align with standard reel packaging requirements specified by ABLIC Inc.
Selection Notes
Select this component when designing boost converters requiring high-frequency operation up to 1.134 MHz. Consider the adjustable duty ratio feature for optimizing efficiency across varying input conditions. Verify that the 8-SON footprint fits the target PCB layout constraints while maintaining thermal performance within the specified temperature range.
Part Context
This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The S-8337 variant specifically allows user-defined maximum duty ratios, distinguishing it from the fixed-duty S-8338 series. Both series share core architecture including UVLO and short-circuit protection mechanisms.
Replacement Considerations
S-8337ACGA-P8T1G shares identical electrical specifications and package type. S-8337AAEB-T8T1G offers similar functionality but utilizes a TSSOP-8 package instead of 8-SON. Verify pin compatibility before substituting between package types.
