产品概述 返回TOP6A3嘉泰姆

The CXMD3256 is a voltage mode, fixed 200kHz/300kHz/600kHz switching frequency,synchronous buck converter. The CXSD6296 allows wide input voltage that is either a single 5~1 2V or two supply voltage(s) for various applications. A power-on-reset (POR) circuit monitors the VCC supply voltage to prevent wrong logic controls. Abuilt- in soft-start circuit prevents the output voltages from over- shoot as well as limits the input current. An internal 0.6V/0.8V Temperature-compensated reference voltage with high accuracy is designed to meet the requirement of low out- put voltage applications. The CXSD6296 provides excel- lent output voltage regulations against load current variation. The controller’s over-current protection monitors the out- put current by using the voltage drop across the RDS (ON) of low-side MOSFET, eliminating the need for a cur- rent sensing resistor that features high efficiency and low cost. In addition, the CXMD3256 also integrates excel- lent protection functions. The over-voltage protection (OVP), under-voltage protection (UVP). OVP circuit which monitors the FB voltage to prevent the PWM output from over voltage, and UVP circuit which monitors the FB voltage to prevent the PWM output from under voltage or short circuit.The CXMD3256 is available in SOP-8P packages
