FP6116
340KHz, 3A, Asynchronous Step-Down Regulator
General Description
The FP6116 is a buck switching regulator for wide operating voltage application fields. The
FP6116 includes a high current P-MOSFET, a high precision reference (0.8V) for comparing output
voltage with a feedback amplifier, an internal soft start timer and dead-time controller. The oscillator is
for controlling the maximum duty cycle and PWM frequency.
Features
Precision Feedback Reference Voltage: 0.8V (2%)
Wide Supply Voltage Operating Range: 3.6 to 23V
Low Current Consumption: 3mA
Internal Fixed Oscillator Frequency: 340KHz (Typ.)
Internal Soft-Start Function (SS)
Built-In P-MOSFET for 3A Output Loading
Over Current Protection
Package: SOP-8L

The inductors in different shape and style are available from manufacturers. Shielded inductors
are small and radiate less EMI issue. But they cost more than unshielded inductors. The choice
depends on EMI requirement, price and size.

Output Capacitor Selection
The output capacitor is required to maintain the DC output voltage. Low ESR capacitors are
preferred to keep the output voltage ripple low. In a buck converter circuit, output ripple voltage is
determined by inductor value, switching frequency, output capacitor value and ESR. The output ripple
is determined by:
VO
IL
ESRCOUT
1
8 f COUT
Where f = operating frequency, COUT= output capacitance and ΔIL = ripple current in the inductor.
For a fixed output voltage, the output ripple is highest at maximum input voltage since ΔIL increases
with input voltage.
Using Ceramic Input and Output Capacitors
Care must be taken when ceramic capacitors are used at the input and the output. When a
ceramic capacitor is used at the input and the power is supplied by a wall adapter through long wires, a
load step at the output can induce ringing at the input, VIN. In best condition, this ringing can couple to
the output and be mistaken as loop instability. In worst condition, a sudden inrush of current through
the long wires can potentially generate a voltage spike at VIN, which may large enough to damage the
part. When choosing the input and output ceramic capacitors, choose the one with X5R or X7R
dielectric formulations. These dielectrics have the best temperature and voltage characteristics of all
the ceramics for a given value and size.
PC Board Layout Checklist
1. The power traces, consisting of the GND trace, the LX trace and the VIN trace should be kept
short, direct and wide.
2. Place CIN near VCC pin as closely as possible to maintain input voltage steady and filter out the
pulsing input current.
