Микросхема TPS562209DDC

The TPS562209 is a single, adaptive on-time, D-CAP2™-mode, synchronous buck converter requiring a
very low external component count. The D-CAP2 control circuit is optimized for low-ESR output capacitors
such as POSCAP, SP-CAP, or ceramic types and features fast transient response with no external
compensation. The switching frequency is internally set at a nominal 650 kHz. The high-side and low-side
switching MOSFETs are incorporated inside the TPS562209 package along with the gate-drive circuitry.
The low drain-to-source on resistance of the MOSFETs allows the TPS562209 to achieve high efficiencies
and helps keep the junction temperature low at high output currents. The TPS562209 dc/dc synchronous
converter is designed to provide up to a 2-A output from an input voltage source of 4.5 V to 17 V. The
output voltage range is from 0.8 V to 6.5 V.
