... Additional features include a Power-Good output, <1µA shut-down current, short-circuit protection, and over-temperature protection. The EL7530 is available in the 10 Ld MSOP package, making the entire converter occupy less than 0.18n area with components on one side only. The 10 Ld MSOP package is specified for operation over the full -40° ...

... The inductor current limit is gradually increased to ensure proper soft-start operation. When the EN pin is connected to a logic low, the EL7530 is in the shut-down mode. All the control circuitry and both MOSFETs are off, and V total input current is less than 1µA. ...

... Thermal Performance The EL7530 is available in a fused-lead MSOP10. Compared with regular MSOP10 package, the fused- lead package provides lower thermal resistance. The θ 100°C 4-layer board and 125°C/W on 2-layer board. Maximizing the copper area around the pins will further improve the thermal performance ...
