FP6293
1MHz, 3.5A Step-Up Current Mode PWM Converter
General Description
The FP6293 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.14Ω
power MOSFET make this regulator highly power efficient. The internal compensation network also
minimizes as much as 6 external component counts. The non-inverting input of error amplifier connects
to a 0.6V precision reference voltage and internal soft-start function can reduce the inrush current.
The FP6293 is available in the DFN-8L/SOP-8L(EP) package and provides space-saving PCB
for the application fields.

FP6293
Function Description
Operation
The FP6293 is a current mode boost converter. The constant switching frequency is 1MHz and
operates with pulse width modulation (PWM). Build-in 18V / 3.5A MOSFET provides a high output
voltage. The control loop architecture is peak current mode control; therefore slope compensation
circuit is added to the current signal to allow stable operation for duty cycles larger than 50%.
Soft Start Function
Soft start circuitry is integrated into FP6293 to avoid inrush current during power on. After the IC
is enabled, the output of error amplifier is clamped by the internal soft-start function, which causes
PWM pulse width increasing slowly and thus reducing input surge current.
Current Limit Program
A resistor between OC and GND pin programs peak switch current. The resistor value should be
between 27k and 192k. The current limit will be set from 3.5A to 0.5A. Keep traces at this pin as short
as possible. Do not put capacitance at this pin. To set the over current trip point according to the
following equation:
96000
IOCP
=
R3
Over Temperature Protection (OTP)
FP6293 will turn off the power MOSFET automatically when the internal junction temperature is
over 150°C. The power MOSFET wake up when the junction temperature drops 30°C under the OTP
threshold temperature.
Over Voltage Protection (OVP)
In some condition, the resistive divider may be unconnected, which will cause PWM signal to
operate with maximum duty cycle and output voltage is boosted higher and higher. The power
MOSFET will be turned off immediately, when the output voltage exceeds the OVP threshold level. The
FP6293’s OVP threshold is 16V.

Application Information
Inductor Selection
Inductance value is decided based on different condition. 3.3uH to 4.7µH inductor value is
recommended for general application circuit. There are three important inductor specifications, DC
resistance, saturation current and core loss. Low DC resistance has better power efficiency. Also, it
avoid inductor saturation which will cause circuit system unstable and lower core loss at 1 MHz.
Capacitor Selection
The output capacitor is required to maintain the DC voltage. Low ESR capacitors are preferred to
reduce the output voltage ripple. Ceramic capacitor of X5R and X7R are recommended, which have
low equivalent series resistance (ESR) and wider operation temperature range.
Diode Selection
Schottky diodes with fast recovery times and low forward voltages are recommended. Ensure the
diode average and peak current rating exceed the average output current and peak inductor current. In
addition, the diode’s reverse breakdown voltage must exceed the output voltage.
Output Voltage Programming
The output voltage is set by a resistive voltage divider from the output voltage to FB. The output
voltage is:
R1
R2
VOUT 0.6V 1
Layout Considerations
1. The power traces, consisting of the GND trace, the LX trace and the VCC trace should be kept
short, direct and wide.
2. LX、L and D switching node, wide and short trace to reduce EMI.
3. Place CIN near VCC pin as closely as possible to maintain input voltage steady and filter out the
pulsing input current.
4. The resistive divider R1and R2 must be connected to FB pin directly as closely as possible.
5. FB is a sensitive node. Please keep it away from switching node, LX.
6. The GND of the IC, CIN and COUT should be connected close together directly to a ground
plane.

Note: Don’t pull the Vout back to the FP6293’s Vcc pin. When the system receives the
