FP6162
1.5MHz, 1.5A Synchronous Step-Down Regulator
General Description
The FP6162 is a high efficiency current mode synchronous buck PWM DC-DC regulator. The
internal generated 0.6V precision feedback reference voltage is designed for low output voltage. Low
RDS(ON) synchronous switch dramatically reduces conduction loss. To extend battery life for portable
application, 100% duty cycle is supported for low-dropout operation. Shutdown mode also helps saving
the current consumption. The FP6162 is packaged in MSOP-10L, DFN-10L and SOP-8L to reduce
PCB space.
Features
Input Voltage Range: 2.5 to 5.5V
Adjustable Output Voltage From 0.6V to VIN
Precision Feedback Reference Voltage: 0.6V (±2%)
Output Current: 1.5A (Max.)
Duty Cycle: 0~100%
Internal Fixed PWM Frequency: 1.5MHz
Low Quiescent Current: 100μA
No Schottky Diode Required

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
ESR COUT
8f
1
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. At best, this ringing can couple to the output
and be mistaken as loop instability. At worst, a sudden inrush of current through the long wires can
potentially cause a voltage spike at VIN, large enough to damage the part. When choosing the input
and output ceramic capacitors, choose the X5R or X7R dielectric formulations. These dielectrics have
the best temperature and voltage characteristics of all the ceramics for a given value and size.
