FP6276B
500kHz 6A High Efficiency Synchronous PWM Boost Converter
General Description
The FP6276B is a current mode 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.
Features
Current mode with PWM/PSM control
Input voltage range: 2.4V~4.5V
Adjustable Output up to 5.3V
Shutdown current: <1uA
Oscillator frequency: 500KHz
Reference voltage: 0.6V +/-2%
Disconnect load during shutdown
Cycle-by-cycle current limit
Low RDS(on): 40mΩ for both high and low side
Protection: OTP, OCP, SCP
Internal compensation
Internal soft-start: 7ms
Package: SOP-8L(EP)
