Description
The BD9862MUV is a 3ch system power supply for mobile TFT liquid crystal panels.Operable at VBAT=1.8V, CH2 & CH3 adopts the original PWM/PFM automatic switching control charge pump and realizes high efficiency in full-load range.
Features
- 1) Input voltage range: 1.8V~4.5V (The input voltage can be 5.5V if a double charge pump is not used) 2) The step-up switching regulator has a built-in output FET (CH1) 3) There is a built-in PWM/PFM automatic switching charge pump circuit with a fixed PWM terminal (CH2,3) 4) Switching regulator oscillation frequency: MHz(typ. ) 5) Charge pump oscillation frequency: 500kHz(typ. ) 6) There is a built-in circuit to discontinue output (timer latch type) in the event of overload 7) Package VQFN024V40.
