Specyfikacja

The TPS55340RTET is a Boost/SEPIC/Flyback DC-DC Regulator with integrated 5A 40V power switch. The device can be configured in several standard switching-regulator topologies, including boost, SEPIC and isolated flyback. The device has a wide input voltage range to support applications with input voltage from multicell batteries or regulated 3.3, 5, 12 and 24V power rails. The TPS55340 regulates the output voltage with current mode PWM (pulse width modulation) control and has an internal oscillator. The switching frequency of PWM is set by either an external resistor or by synchronizing to an external clock signal. The user can program the switching frequency from 100kHz to 1.2MHz. The device features a programmable soft-start function to limit inrush current during start-up and has other built-in protection features including cycle-by-cycle over-current limit and thermal shutdown.
  • Internal 5A, 40V low-side MOSFET switch
  • ±0.7% Reference voltage
  • 0.5mA Operating quiescent current
  • 2.7µA Shutdown supply current
  • Fixed frequency current mode PWM control
  • Frequency adjustable from 100kHz to 1.2MHz
  • Synchronization capability to external clock
  • Adjustable soft-start time
  • Pulse skipping for higher efficiency at light loads
  • Cycle-by-cycle current limit, thermal shutdown and UVLO protection
  • Green product and no Sb/Br

Zastosowania

Zarządzanie zasilaniem, Urządzenia przenośne, Komputery i urządzenia peryferyjne, Przemysłowe

Ostrzeżenia

This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
