Overview
The S-8337ABCC-P8T1G is a CMOS step-up switching regulator controller from the S-8337 series, manufactured by ABLIC Inc. It operates with a minimum supply voltage of 1.8 V and supports an internal oscillation frequency up to 1.133 MHz via an external resistor on the ROSC pin. The maximum PWM duty ratio is adjustable through an external resistor connected to the RDuty pin. Phase compensation and gain are configurable using components on the CC pin. The device includes under-voltage lockout and timer latch short-circuit protection circuits.
Feature Summary
- Integrates reference voltage, oscillator, error amplifier, and PWM controller within a single CMOS chip.
- Features low minimum operating voltage suitable for portable systems.
- Includes built-in under-voltage lockout and timer latch short-circuit protection.
Applications
- Power supply for LCD panels
- Portable electronic systems requiring low voltage operation
Procurement Notes
Verify the specific suffix 'P8T1G' against official ABLIC documentation to confirm package type and reel specifications. Ensure compatibility with required operating temperature ranges and control characteristics before integration into designs.
Selection Notes
Select this component when designing boost converters requiring adjustable switching frequencies and duty ratios. Consider the need for external resistors for frequency setting and phase compensation. Verify that the 1.8 V minimum operating voltage aligns with the system's power source capabilities.
Part Context
This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. It is designed as a CMOS solution for step-up applications, offering flexibility in frequency and duty cycle settings compared to fixed-function alternatives.
Replacement Considerations
The S-8337ACCC-P8T1G serves as a direct functional substitute within the same series, sharing identical core architecture and control features while differing only in specific manufacturing or packaging suffixes.
