Dual 3A 1MHz/2.5MHz High Efficiency Synchronous
Buck Regulator
ISL8036, ISL8036A
ISL8036, ISL8036A are integrated power controllers rated for
dual 3A output current or current sharing operation with a
1MHz (ISL8036)/2.5MHz (ISL8036A) step-down regulator,
which is ideal for any low power low-voltage applications. 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 2.8V to
6V, allowing for the use of a single Li+ cell, three NiMH cells or
a regulated 5V input. The two channels are 180° out-of-phase,
and each one has a guaranteed minimum output current of
3A. They can be combined to form a single 6A output in the
current sharing mode. While in current sharing, the interleaved
PWM signals reduce input and output ripple.
The ISL8036, ISL8036A 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 each.
The ISL8036, ISL8036A offers an independent 1ms
Power-good (PG) timer at power-up. When shutdown, ISL8036,
ISL8036A discharges the output capacitor. Other features
include internal digital soft-start, enable for power sequence,
overcurrent protection, and thermal shutdown.
The ISL8036, ISL8036A is offered in a 24 Ld 4mmx4mm QFN
package with 1mm maximum height. The complete converter
occupies less than 1.5cm 2 area.
