PWM Controller With SCP / DTC Function
The FP5001 is a single chip pulse -width-modulation controlle r co mposed of an open colle ctor
transistor output, an error amplifier and duty control comparators (DTC). The FP5001 contains a 1.0V
precision voltage referen ce regulato r, unde r-voltage lockout ci rcuit (UVLO), sho rt circuit prote ction
circuit (SCP). It is applied to offer spa ce and lo w cost in many appli cations su ch as the DC / DC
converter and backlight inverter.
Using FP500 1, it is easy to complete a powe r conversion reg ulator de sign with few external
components. The circuit diagram of the typical application example is shown as below.
Wide Operating Voltage Range: 3.6~40V
Reference Voltage Precision: 2%
Oscillator Frequency: 500KHz Max.
Output sink current up to 100mA
Low Quiescent Supply Current
Variable Dead-time Control (DTC)
