The EL7532 is a synchronous, integrated FET 2A 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 single Li-Ion battery source. The output can be externally set from 0. 8V to VIN with a resistive divider. The EL7532 features PWM mode control. The operating frequency is typically 1. 5MHz. Additional features include a 100ms Power-On-Reset output, <1µA shut-down current and over-temperature protection. The EL7532 is available in the 10-pin MSOP package, making the entire converter occupy less than 0. 18 in2 of PCB area with components on one side only. The package is specified for operation over the full -40°C to +85°C temperature range.
