电压型异步PWM控制CXSD62375工作电压可达20V电压模式降压型脉宽调制转换器宽输入电源驱动高达3A的负载

The CXSD62375 is a voltage-mode buck PWM converter capable of driving up to 3A loads over a wide input supply range. High efficiency is obtained through the use of a low RDS(ON) P-channel power switch. The internal compensation makes feedback control have excellent line and load regulation characteristics without external designs. It uses a fixed switching frequency of 300KHz. The output voltage is 3.3V, 5V and an user-programmable version via an external resistive voltage divider. The built-in soft-start can reduce inrush current on the input source at turn on. The device also has built-in current-limit, thermal shutdown, under-voltage lockout and an ON/OFF logic-control that can power down the regulator to a shutdown mode. When current limit function occurred and VFB is down to 0.3V below, the device changes switching frequency to 120KHz to protect IC from damage. CXSD62375 is available in SOP-8 package.
