- 描 述： The LP78086 are PMU, and contain a 650mA Buck
DC/DC and dual channel 350mA Linear Regulator,
Buck DC/DC is a constant frequency, current mode,
PWM step-down converter. The device integrates a
main switch and a synchronous rectifier for high
efficiency. The 2.1V to 6.5V input voltage range makes
the LP78086 is ideally suited for portable electronic
devices that are powered from 1-cell Li-ion battery or
from other power sources within the range such as
cellular phones, PDAs and handy-terminals. Internal
synchronous rectifier with low RDS(ON) dramatically
reduces conduction loss at PWM mode. The internal
synchronous switch increases efficiency while
eliminate the need for an external Schottky diode.The
switching ripple is easily smoothed-out by small
package filtering elements due to a fixed operation
frequency of 1.5MHz. This along with small TDFN-10
package provide small PCB area application. Other
features include soft start, lower internal reference
voltage with 2%
