Overview
The S-8337AAIC-T8T1G is a CMOS step-up switching regulator controller from the S-8337 series, manufactured by ABLIC Inc. It operates within an input voltage range of 1.8 V to 6 V and utilizes pulse width modulation (PWM) control. The device supports an internal oscillation frequency adjustable up to 1.133 MHz via an external resistor on the ROSC pin. It features a timer latch short-circuit protection circuit and under-voltage lockout (UVLO). The component is housed in an 8-pin TSSOP package.
Feature Summary
- Integrates a reference voltage circuit, oscillator, error amplifier, and PWM controller for efficient power management.
- Features a timer latch short-circuit protection circuit to enhance system reliability.
- Includes an under-voltage lockout (UVLO) circuit for stable operation at low input voltages.
Applications
- Power supply for LCD displays
- Portable systems operating on low voltage
Procurement Notes
Verify the specific suffix 'AAIC' against official ABLIC documentation to confirm exact electrical characteristics, as variations exist within the S-8337 family. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors, as availability may vary.
Selection Notes
Select this component when designing boost converter circuits requiring high-frequency operation up to 1.133 MHz. Ensure the external components connected to the ROSC, RDuty, and CC pins are properly sized to set the desired frequency, duty ratio, and phase compensation for stability.
Part Context
This part belongs to the S-8337/8338 Series, which are CMOS step-up switching regulator controllers designed for low-voltage applications. The series distinguishes itself through adjustable maximum duty ratios in the S-8337 variant, unlike the fixed ratio in the S-8338 variant.
Replacement Considerations
The S-8338ABEC-T8T1G is a related model within the same series but features a fixed maximum duty ratio. Verify if the application requires the adjustable duty ratio capability unique to the S-8337 series before considering substitutes.
