LM3743

具有完整故障保护功能的高性能同步降压控制器

The LM3743 is a DC-DC voltage mode PWM buck controller featuring synchronous rectification at 300 kHz or 1 MHz. It can deliver current as high as 20A and step down from an input voltage between 3V and 5.5V down to a minimum output voltage of 0.8V, with a ±1.75% internal reference accuracy. The L • Input Voltage From 3.0V to 5.5V\n• Reference Accuracy: ±1.75%, over Full Temperature and Input Voltage Range\n• Switching Frequency Options of 1 MHz or 300 kHz\n• Low-Side Current Limit\n• Hiccup Mode Protection Eliminates Thermal Runaway During Fault Conditions\n• Pre-Bias Start-Up Capability;
