ISL9305H規(guī)格書詳情
The ISL9305H is an integrated mini Power Management IC
(mini-PMIC) for powering low-voltage microprocessor, or
applications using a single Li-Ion or Li-Polymer cell battery to
power multiple voltage rails. ISL9305H 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 1.5A load current.
The default output voltage can be set from 0.8V to VIN using
external feedback resistors on the adjustable version, or the
ISL9305H can be ordered in factory pre-set power-up default
voltages in increments of 100mV from 0.9V to 3.6V.
The ISL9305H 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 output comes with
factory pre-set fixed output voltage options between 0.9V to 3.3V.
The ISL9305H is available in a 4mmx4mm 16 Ld TQFN
package.
