TPS543B20RVFT

DC/DC POL преобразователь, регулируемый, понижающий, 2МГц, 4В до 19В вход, 0.6В до 5.5В/25А выход.

The TPS543B20 employs an internally compensated emulated peak-current-mode control, with a clock synchronizable, fixed-frequency modulator for EMI-sensitive POL. The internal integrator and directly amplifying ramp tracking loop eliminate the need for external compensation over a wide range of frequencies thereby making the system design flexible, dense, and simple.

• Internally-Compensated advanced current mode control 25-A POL
• Integrated 4.1/1.9-mR stacked NexFET™ power stage with lossless low-side current sensing
• Fixed frequency - synchronization to an external clock and/or sync out
• Differential remote sensing
• Safe start-up into pre-biased output
• High-accuracy hiccup current limit
