The EL7534 is a synchronous, integrated FET 600mA stepdown
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 EL7534 features PWM mode control. The operating
frequency is typically 1.5MHz. Additional features include a
100ms Power-On-Reset output, <1μA shut-down current,
short-circuit protection, and over-temperature protection.
The EL7534 is available in the 10 Ld MSOP package,
making the entire converter occupy less than 0.15 in2 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.
