The EL7536 is a synchronous, integrated FET 1A step-down
regulator with internal compensation. It operates with an
input voltage range from 2.5V to 5.5V, which accommodates
supplies of 3.3V, 5V, or a Li-Ion battery source. The output
can be externally set from 0.8V to VIN with a resistive
divider.
The EL7536 features PWM mode control. The operating
frequency is typically 1.4MHz. Additional features include a
100ms Power-On-Reset output, <1μA shut-down current,
short-circuit protection, and over-temperature protection.
The EL7536 is available in the 10 Ld MSOP package,
making the entire converter occupy less than 0.15in2 of PCB
area with components on one side only. Both packages are
specified for operation over the full -40°C to +85°C
temperature range.
