APW8722
ANPEC Electronics
5V to 12V Single Buck Voltage Mode PWM Controller
Package Type: SOP-8P
The APW8722 is a voltage mode, fixed 200kHz/300kHz/ 600kHz switching frequency, synchronous buck converter. The APW8722 allows wide input voltage that is either a single 5~12V or two supply voltage(s) for various applications. A power-on-reset (POR) circuit monitors the VCC supply voltage to prevent wrong logic controls. Abuiltin soft-start circuit prevents the output voltages from overshoot as well as limits the input current. An internal 0.6V temperature-compensated reference voltage with high accuracy is designed to meet the requirement of low output voltage applications. The APW8722 provides excellent output voltage regulations against load current variation. The controller’s over-current protection monitors the output current by using the voltage drop across the RDS (ON) of low-side MOSFET, eliminating the need for a current sensing resistor that features high efficiency and low cost. In addition, the APW8722 also integrates excellent 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 APW8722 is available in SOP-8P packages.
