EL7530 Monolithic 600mA Step-Down Regulator with Low Quiescent Current

The EL7530 is a synchronous, integrated FET 600mA 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 EL7530 features automatic PFM/PWM mode control, or PWM mode only. The PWM frequency is typically 1.4MHz and can be synchronized up to 12MHz. The typical no load quiescent current is only 120uA. Additional features include a Power-Good output, <1uA shut-down current, short-circuit protection, and over-temperature protection.

The EL7530 is available in the 10-pin MSOP package, making the the entire converter occupy less than 0.18n2 of PCB area with components on one side only. The 10-pin MSOP package is specified for operation over the full -40°C to +85°C temperature range.
