General Description
The FP6276 is a current mode synchronous boost DC-DC converter with PWM/PSM control. Its
PWM circuitry with built-in 40mΩ high side switch and 40mΩ low side switch make this regulator highly
power efficient. The internal compensation network also minimizes external component counts to only
6. An internal 0.6V voltage is connected to error amplifier the non-inverting input as precision reference
voltage. Built-in soft-start function can reduce the inrush current.
