FP5101 / FP5101A
1 Channel Synchronous PWM Controller
General Description
The FP5101 / A is a DC-DC synchronous buck converter controller IC. It comprises high, low side
NMOS gate drivers, boot diode, internal soft start, and over current protection circuit. With +2V to +12V
VIN supply voltage, it is suitable for a wide range of applications.
Features
+12V Vcc Supply Voltage
Feedback Reference Voltage: 0.8V (±2%)
Fixed Frequency Oscillator: 300 / 600KHz
Peak Output Driving Capability: 500mA
Internal Soft Start Function
High-Gain Voltage Mode PWM Control
Over Current Protection by detecting Low-side MOS voltage drop
Package: SOP8 (EP)

parameters in the above equation should be considered.
-The RDS (ON) of MOSFET varies with temperature and gate to source voltage, the user should
determine the maximum RDS (ON) in manufacturer’s datasheet.
-The parasitic series resistance in PCB’s trace must be considered and added to RDS (ON) in the
above equation.
-The minimum IOCSET (=-0.21V / RDS (ON)) should be considered over the above equation.
Note that the IOCSET is the current flow through the low side MOSFET. IOCSET must be greater than
maximum output current add the half of inductor ripple current. That is,

To avoid the gate transition noise and ringing on the SW pin, the actual monitoring of the
bottom-side MOSFET's on-resistance starts 200ns (nominal) after the LGATE rising edge. The
