APW8720B

Single Buck Voltage Mode PWM Controller

The APW8720B is a voltage mode, fixed 300kHz switching frequency, synchronous buck converter. The APW8720B allows wide input voltage that is either a single 5~12V or two supply voltage(s) for various applications. A ( APW8720B ) power-on-reset (POR) circuit monitors the VCC supply voltage to prevent wrong logic controls. A built-in soft-start ( APW8720B ) circuit prevents the output voltages from overshoot as-well as limits the input current. An internal 0.8V temperature compensated reference voltage with high accuracy is ( APW8720B ) designed to meet the requirement of low output voltage applications. The APW8720B provides excellent ( APW8720B ) output voltage regulations against load current variation.Simplified Application Circuit The controller’s over-current protection monitors the output current by using the ( APW8720B ) voltage drop across the RDS(ON) of low-side MOSFET, eliminating the need for a current sensing resistor that ( APW8720B ) features high efficiency and low cost. In addition, the APW8720B also integrates excellent protection functions: The ( APW8720B ) over-voltage protection (OVP) , undervoltage protection (UVP). OVP circuit which monitors the,FB voltage to prevent the PWM output from over-voltage and UVP circuit which ( APW8720B ) monitors the FB voltage to prevent the PWM output from under-voltage or short-circuit The APW8720B is available in SOP-8P and TDFN3x3-10 package
