NCP1337DR2G Description

Short technical summary and product information.

The NCP1337DR2G from ON Semiconductor is a PWM current-mode controller optimized for free-running quasi-resonant operation. This device integrates a demagnetization detector, ensuring Borderline/Critical Conduction Mode across various load and line conditions with minimum drain voltage switching. Its internal frequency is limited to 130 kHz, preventing operation above the 150 kHz CISPR-22 EMI limit.

 

The controller features a soft-skip mode for standby efficiency, reducing power demand below a predetermined level. It includes auto-recovery short-circuit protection, overvoltage protection, and brown-out protection. An internal 4.0 ms soft-start function minimizes startup stress. The NCP1337DR2G is suitable for applications such as AC-DC adapters, offline battery chargers, and auxiliary power supplies.

 

This component is supplied in a 7-SOIC package designed for surface mounting. It operates within a voltage range of 10V to 20V and has an operating temperature range of -40°C to 150°C (TJ). The device offers isolated output and features fault protection including current limiting, over temperature, over voltage, and short circuit protection.
