ISL85003A規(guī)格書詳情
The ISL85005 and ISL85005A are monolithic, synchronous
buck regulators with integrated 5A, 18V high-side and low-side
FETs. These devices also provide an integrated bootstrap diode
for the high-side gate driver to reduce the external parts count.
These devices have a wide input voltage range to support
applications with input voltage from multi-cell batteries or
regulated 5V and 12V power rails.
The ISL85005 and ISL85005A regulate the output voltage
with current mode control and have an internal oscillator. The
switching frequency of the ISL85005 is internally set as
500kHz, and can be synchronized to an external clock signal
with frequency ranges from 300kHz to 2MHz. The ISL85005A
has a fixed 500kHz switching frequency.
The ISL85005 has a fixed 2.3ms soft-start, while the
ISL85005A features programmable soft-start to limit inrush
current during startup. With SS pin floating, the soft-start time
of ISL85005A is also 2.3ms.
The ISL85005 can be configured in either forced Continuous
Conduction Mode (CCM) or Diode Emulation Mode (DEM). DEM
enables high efficiency at light-load conditions. The
ISL85005A always operates in forced CCM.
The ISL85005 and ISL85005A have built-in protections
including input UVLO protection, input and output overvoltage
protection, high-side cycle-by-cycle current limit, low-side
forward current limit and reverse current limit, and thermal
shutdown.
