Dual 3A Low Quiescent Current High Efficiency
Synchronous Buck Regulator
ISL8033, ISL8033A
ISL8033 is a dual integrated power controller rated for 3A per
channel with a 1MHz step-down regulator that is ideal for any low
power low-voltage applications. The ISL8033A offers 2.5MHz
operation for smaller more compacted design. The channels are
180° out-of-phase for input RMS current and EMI reduction. It is
optimized for generating low output voltages down to 0.8V each.
The supply voltage range is from 2.85V to 6V, allowing for the use
of a single Li+ cell, three NiMH cells or a regulated 5V input. It
has a guaranteed minimum output current of 3A each when ISET
is connected to VDD. The output current of each output is
selectable by setting ISET pin.
The ISL8033, ISL8033A includes a pair of low ON-resistance
P-Channel and N-Channel internal MOSFETs to maximize
efficiency and minimize external component count. 100% duty-
cycle operation allows less than 250mV dropout voltage at 3A.
The ISL8033, ISL8033A offers an independent 1ms Power-Good
(PG) timer at power-up. When shutdown, ISL8033, ISL8033A
discharges the output capacitor. Other features include internal
digital soft-start, enable for power sequence, controllable soft-
stop output discharge during disabled, start-up with pre-biased
output, 100% maximum duty cycle for lowest dropout, 100%
duty cycle operation for smooth transition, less than 8μA logic
controlled shutdown current, independent enable, overcurrent
protection, and thermal shutdown.
The ISL8033, ISL8033A is offered in a 24 Ld 4mmx4mm QFN
package with 1mm maximum height. The complete converter
occupies less than 5.46cm 2 area.
