ETA/钰泰 ETA8059DJH 峰值电流模式PWM控制器 DFN5x6-7封装

DESCRIPTION

ETA8059DJH is a high performance peak current mode PWM controller. It integrates a 0 48Q/650V high reliability and high stability N-channel Power MOSFET. ETA8059 employs Quasi-Resonant and frequency fold-back technique to reduce EMI and improve average efficiency and meets the latest Level VI eflciency standard with enough margins.

ETA8059DJH is a multi-mode QR/CCM controller. It has burst mode, PFMPWM mode, constant power (CP) mode and power reduction (PR) mode. In full load conditions, ETA8059 can work in both CCM mode and DCM mode to meet different types of applications. Quasi-Resonant (QR) function works all the time in DCM modes. Its burst mode operation enables low standby power with small output voltage ripple. And it achieves very low standby power, good dynamic response and accurate voltage regulation with an opto-coupler and the secondary side control circuit.

With build-in fast start process, ETA8059 can get output voltage very short rise time even with a big capacitive load. And a soft start circuit keeps output voltage no overshoot at power up.

ETA8059 integrates comprehensive protection. In case of over temperature, input/output over voltage, winding short, current sense resistor short and, output short conditions, it would enter auto restart if recovering from fault mode. Cycle- by-Cycle current limiting ensures safe operation even during fault mode and recovering.

ETA8059DJH/AS6 is for applications up to 30 Watts.

ETA8059ES6 is for applications up to 35 Watts.

ETA8059E10 is for applications up to 40 Watts.
