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 120µA. Additional features include a Power-Good output, <1µA shut-down current, short-circuit protection, and over-temperature protection. The EL7531 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. The 10 Ld MSOP package is specified for operation over the full -40°C to +85°C temperature range. Ordering Information PART TAPE & PART N.
