深圳市百盛新纪元半导体有限公司介绍:

FP6277是台湾远翔科技生产

输入电压：2.4V至4.5V

输出电压：最大5.3V

输出电流：3A，或者3A以下。

导向：

（导向型号，均可在我们公司网站查到相关介绍）

如果输出电流需要2.4A，可以看FP6276B，

如果输出电流需要1A及以下，可以看PS7516。

The FP6277 is a current mode boost DC DC converter with PWM/PSM control. Its PWM circuitry

with built-in 30mΩ high side switch and 30mΩ 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特点：
 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): 30mΩ for both high and low side
 Protection: OTP, OCP, SCP
 Internal compensation
 Internal soft-start: 7ms
 Package: SOP-8L(EP)

Applications应用：
 Chargers
 Handheld Devices
 Portable Products
 Power Bank
