ISL9307IRTAANYEV1Z规格书详情
The ISL9307 is an integrated mini Power Management IC
(mini-PMIC) ideal for applications for powering low-voltage
microprocessor or multiple voltage rails with a battery as an
input source, such as a single Li-ion or Li-polymer. ISL9307
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 efficiency and maximize battery life.
The ISL9307 features EN pins for each channel, thus allowing
startup delay for power sequencing.
The ISL9307 also provides two 300mA low-dropout (LDO)
regulators. The input voltage range is 1.5V to 5.5V, which
allows them to be powered from one of the on-chip step-down
converters or directly from a battery. The default LDO power-up
output comes with factory pre-set fixed output voltage options
between 0.9V and 3.3V.
The ISL9307 is available in a 4mmx4mm 16 Ld TQFN.
