Overview
The S-8337AABB-T8T1G 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 internal oscillation frequency is adjustable up to 1.133 MHz via an external resistor connected to the ROSC pin. The maximum duty ratio is configurable through an external resistor on the RDuty pin. Phase compensation and gain are adjusted using external components on the CC pin. The device features under-voltage lockout and timer latch short-circuit protection, packaged in an 8-TSSOP housing.
Feature Summary
- Integrates reference voltage, oscillator, error amplifier, PWM controller, UVLO, and short-circuit protection circuits.
- Supports high-frequency operation with an adjustable internal oscillation frequency settable up to 1.133 MHz.
- Allows user-defined maximum duty ratio configuration via an external resistor connected to the RDuty pin.
Applications
- Power supply for LCD panels
- Portable systems operating on low voltage
Procurement Notes
Verify the specific suffix code against official documentation to confirm exact electrical characteristics, as variations exist within the S-8337 family. Confirm RoHS compliance status and package type details directly with the manufacturer or authorized distributors before procurement.
Selection Notes
Select this component when designing boost converter circuits requiring low minimum operating voltage and adjustable switching frequencies. Ensure external components for the ROSC, RDuty, and CC pins are chosen to meet specific stability and transient response requirements defined in the datasheet.
Part Context
This part belongs to the S-8337/8338 Series of CMOS step-up switching regulator controllers. The S-8337 variant distinguishes itself from the S-8338 series by offering adjustable maximum duty ratios, whereas the S-8338 has a fixed maximum duty ratio. Both share similar core architectures and protection features.
