ISL9305規(guī)格書詳情
The ISL9305 is an integrated mini Power Management IC
(mini-PMIC) ideal for applications of powering low-voltage
microprocessor or multiple voltage rails with battery as input
sources, such as a single Li-ion or Li-Polymer. ISL9305
integrates two high-efficiency 3MHz synchronous step-down
converters (DCD1 and DCD2) and two low-input, low-dropout
linear regulators (LDO1 and LDO2).
The 3MHz PWM switching frequency allows the use of very small
external inductors and capacitors. Both step-down converters can
enter skip mode under light load conditions to further improve the
efficiency and maximize the battery life. For noise sensitive
applications, they can also be programmed through I2C interface
to operate in forced PWM mode regardless of the load current
condition. The I2C interface supports on-the-fly slew rate control of
the output voltage from 0.825V to 3.6V at 25mV/step size for
dynamic power saving. Each step-down converter can supply up to
800mA load current. The default output voltage can be set from
0.8V to VIN using external feedback resistors on the adjustable
version, or the ISL9305 can be ordered in factory pre-set voltage
options from 0.9V to 3.6V in 50mV step.
The ISL9305 also provides two 300mA low dropout (LDO)
regulators. The input voltage range is 1.5V to 5.5V allowing
them to be powered from one of the on-chip step-down
converters or directly from the battery. The default LDO
power-up output comes with factory pre-set fixed output
voltage options between 0.9V to 3.3V.
The ISL9305 is available in a 4mmx4mm 16 Ld TQFN package.
