DC-DC 10A D PG-SSOP-14 SMD Description

The TLF51801ELV is a PWM step-down DC/DC controller with external power switches, packaged in a small, thermal enhanced PG-SSOP-14 with exposed pad. The regulator is capable to drive external power-stages (n/n-MOS) for loads up to 10 A. The current limitation function is using either the Rdson of the HS-switch or a external shunt resistor. The output voltage with a 2% tolerance is adjustable. The device can run with a duty cycle larger than 99%. The bootstrap diode is integrated to save external components. The switching frequency can be set between 100 kHz and 700 kHz or can be synchronized to an external clock. During start-up the integrated soft-start limits the in rush current peak and prevents from an output voltage overshoot. The enable function, in shutdown mode with less than 2 μA current consumption, enables easy power management in battery-powered systems. The TLF51801ELV includes protection features such as a cycle-by-cycle current limitation, over-temperature shutdown and input under voltage lockout. With a temperature range Tj from -40°C to 150°C the device is suitable for harsh environment of automotive applications
