S-8337ACDC-P8T1G

Overview

The S-8337ACDC-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 supports an internal oscillation frequency adjustable up to 1.134 MHz via external components. It features a maximum duty ratio of 0.89 and includes protection circuits such as under-voltage lockout and timer latch short-circuit protection. The component is housed in an 8-SON package with dimensions of 2.9 mm x 2.8 mm.

Feature Summary

• Integrates reference voltage, oscillator, error amplifier, and PWM controller for efficient power management
• Features timer latch short-circuit protection and under-voltage lockout circuitry
• Allows external adjustment of oscillation frequency and maximum duty ratio

Applications

• Power supplies for LCD panels
• Portable systems operating on low voltage
• Step-up DC-DC converter designs

Procurement Notes

Verify the specific suffix P8T1G against official datasheets to confirm the 8-SON package type and lead-free status. Confirm RoHS compliance and REACH registration details directly with ABLIC documentation before procurement. Ensure design compatibility with the specified operating temperature range and electrical parameters.

Selection Notes

Select this component when a compact boost controller with adjustable frequency is required for low-voltage applications. Consider the 8-SON package for space-constrained designs. Verify that the external component values align with the desired switching frequency and duty cycle settings defined in the official 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 portable electronics requiring efficient step-up regulation from low input voltages. The S-8337 variant specifically allows user-defined maximum duty ratios, distinguishing it from fixed-duty counterparts.

Replacement Considerations

S-8337AAEB-P8T1G and S-8337ACFA-P8T1G are confirmed substitutes within the same series offering identical functional characteristics and package types.
