S-8333ACEA-T8T1G

Overview

The S-8333ACEA-T8T1G is a CMOS step-up switching regulator controller from the ABLIC S-8333 Series. It integrates a reference voltage circuit, oscillator, error amplifier, PWM controller, under-voltage lockout (UVLO), and timer latch short-circuit protection. The device operates with an input voltage range of 1.8 V to 6 V and supports internal oscillation frequencies up to 1.08 MHz via an external resistor on the ROSC pin. Maximum duty ratio is adjustable through an external resistor on the RDuty pin. Phase compensation and gain are configurable using components connected to the CC pin. It is housed in an 8-pin TSSOP package.

Feature Summary

• Integrates UVLO and timer latch short-circuit protection for enhanced system reliability
• Features adjustable maximum duty ratio via external resistance for flexible output control
• Supports phase compensation adjustment for optimized transient response and stability

Applications

• Power supply circuits for LCD panels
• Portable electronic systems operating on low voltage sources
• Step-up DC-DC converter designs requiring high-frequency operation

Procurement Notes
