FP6165
1.5MHz, 3A Synchronous Step-Down Regulator
General Description
The FP6165 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 FP6165 is packaged in MSOP-10L, DFN-10L and SOP-8L to reduce
PCB space.

PC Board Layout Checklist
1. The power traces, consisting of the GND, SW and VIN trace should be kept short, direct and
wide.
2. Place CIN near VIN pin as closely as possible to maintain input voltage steady and filter out the
pulsing input current.
3. The resistive divider R1 and R2 must be connected to FB pin directly and as closely as
possible.
4. FB is a sensitive node. Please keep it away from switching node, SW. A good approach is to
route the feedback trace on another PCB layer and have a ground plane between the top and
feedback trace routing layer. This reduces EMI radiation on to the DC-DC converter its own
voltage feedback trace.
5. Keep the GND plates of CIN and COUT as close as possible. Then connect this to the ground
plane (if one is used) with several vias. This reduces ground plane noise by preventing the
switching currents from circulating through the ground plane. It also reduces ground bounce at
FP6161 by giving it a low impedance ground connection.
