ML4866 General Description
The ML4866 is a high efficiency pulse width modulated (PWM) buck regulator designed for use in 5V systems or portable equipment that need a compact, efficienct 3.3V supply. It has a switching frequency of 120kHz and uses synchronous rectification to optimize power conversion efficiency. Unlike other solutions, the ML4866 requires no external diodes or FETs.
The ML4866 can provide up to 500mA of output current, and operates over an input voltage range of 3.5V to 6.5V (3 to 4 cells or a 5 VDC supply). A complete switched mode power converter can be quickly and easily implemented with few external components. Thanks to a built-in autoburst mode, power conversion efficiency of this DCDC converter can exceed 90% over more than 2 decades of output load current.
Stability and fast loop response are provided by current programming and a current sense circuit. The ML4866 also has a SHDN pin for use in systems which have power management control. Undervoltage lockout and soft start are also built in.
