The EL7531 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 120A. Additional features include a Power-Good output, <1A shut-down current, short-circuit protection, and over-temperature protection. The EL7531 is available in the 10-pin MSOP and 10-pin DFN (3x3 mm) packages, 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 -40C to +85C temperature range.
