Product Description

The TPS54340DDAR is a 42V input, 3.5A, step down DC/DC converter with Eco-mode in 8 pin HSOIC package. This step down regulator with an integrated high side MOSFET survives load dump pulses up to 45V per ISO 7637. Current mode control provides simple external compensation and flexible component selection. A low ripple pulse skip mode reduces the no load supply current to 146µA. Shutdown supply current is reduced to 1µA when the enable pin is pulled low. Undervoltage lockout is internally set at 4.3V but can be increased using the enable pin. The output voltage start up ramp is internally controlled to provide a controlled start up and eliminate overshoot. A wide switching frequency range allows either efficiency or external component size to be optimized. Frequency foldback and thermal shutdown protects internal and external components during an overload condition. It is used in 12V, 24V industrial, automotive and communication power systems.
3.5A continuous current, 4.5A minimum peak inductor current limit & 1µA shutdown current
Operating temperature range from -40°C to 125°C
Current mode control DC-DC converter, 92mohm high side MOSFET
High efficiency at light loads with pulse skipping Eco-mode, 146µA operating quiescent current
Low dropout at light loads with integrated BOOT recharge FET
100KHz to 2.5MHz fixed switching frequency, 0.8V 1% internal voltage reference
Synchronizes to external clock, adjustable UVLO voltage and hysteresis
Internal soft-start, accurate cycle-by-cycle current limit
Thermal, overvoltage and frequency foldback protection
Supported by WEBENCH software tool
ESD sensitive device, take proper precaution while handling the device.
