ISL8026AEVAL3Z规格书详情
The ISL8026, ISL8026A are highly efficient, monolithic,
synchronous step-down DC/DC converters that can deliver 6A of
continuous output current from a 2.5V to 5.5V input supply. The
devices use current mode control architecture to deliver a very low
duty cycle operation at high frequency with fast transient
response and excellent loop stability.
The ISL8026, ISL8026A integrate a very low ON-resistance
P-Channel (36mΩ) high-side FET and N-Channel (13mΩ)
low-side FET to maximize efficiency and minimize external
component count. The 100 duty-cycle operation allows less
than 180mV dropout voltage at 6A output current. The
operation frequency of the Pulse-width Modulator (PWM) is
adjustable from 500kHz to 4MHz. The default switching
frequency, which is set by connecting the FS pin high, is 1MHz
for the ISL8026 and 2MHz for the ISL8026A.
The ISL8026, ISL8026A can be configured for discontinuous or
forced continuous operation at light load. Forced continuous
operation reduces noise and RF interference, while
discontinuous mode provides higher efficiency by reducing
switching losses at light loads.
Fault protection is provided by internal hiccup mode current
limiting during short-circuit and overcurrent conditions. Other
protection, such as overvoltage and over-temperature, are also
integrated into the device. A power-good output voltage
monitor indicates when the output is in regulation.
The ISL8026, ISL8026A offer a 1ms Power-good (PG) timer at
power-up. When in shutdown, the ISL8026, ISL8026A
discharge the output capacitor through an internal soft-stop
switch. Other features include internal fixed or adjustable
soft-start and internal/external compensation.
The ISL8026, ISL8026A are offered in a space saving 16 Ld
3x3 Pb-free TQFN package with an exposed pad for improved
thermal performance and 0.8mm maximum height. The
complete converter occupies less than 0.22 in2 area.
