Part Number:TPA3255EVM
Hi ti team,
使用AP测试 TPA3255EVM,发现TPA3255RVM会出现保护。请帮忙分下原因
测试条件:
1,AP输入信号800mV;输入频率100HZ;对AP输入信号不断的打开和关断,TPS3255会出现保护。如附件视频
2,功率120W,4R负载,PVDD=51V。
(function(id)
{
var v = document.getElementById(id);var op = v.style.position, ol = v.style.left, or = v.style.right, fe = [];
var nodeLimit = 50;
checkVideo = function() {
if (!v.canPlayType || v.error) {
var bound = 0;
while (v.childNodes.length > 0 && bound < nodeLimit) {
bound++;
if (v.childNodes[0].nodeName != 'SOURCE') {
v.parentNode.insertBefore(v.childNodes[0], v);
}
}
v.parentNode.removeChild(v);
} else if (v.readyState == 0) {
window.setTimeout(checkVideo, 249);
}
},
checkVideoRendered = function() {
if (v.networkState == 1 && v.readyState == 4) {
v.style.position = op;
v.style.left = ol;
v.style.right = or;
for (var i = 0; i < fe.length; i++) {
fe[i].parentNode.removeChild(fe[i]);
}
} else {
window.setTimeout(checkVideoRendered, 249);
}
}
if (navigator.userAgent.indexOf('iPad') == -1 && navigator.userAgent.indexOf('iPhone') == -1 && navigator.userAgent.indexOf('iPod') == -1) {
window.setTimeout(checkVideo, 249);
}
})('v_a6fe6c4366474458bfacf7378cb3c4c1');
