The device uses a 87mOhm high-side N-channel MOSFET with external Schottky catch diode for non-synchronous operation. The 2.2MHz maximum switching frequency allows compact inductor and capacitor selection, while the 146uA quiescent current extends battery life in always-on applications. The B version features a minimum 6.5A switch current limit (vs 5.5A for the original version) and spread-spectrum clock dithering for EMI reduction. The external compensation network provides flexibility for various output filter configurations. The DDA suffix denotes HSOIC-8 PowerPAD with tape and reel packaging.","working_principle":"The TPS54560BDDAR operates as a peak current-mode non-synchronous buck converter. (1) The integrated N-channel high-side MOSFET (87mOhm) connects the input voltage to the inductor during the on-time. During the off-time, the external Schottky diode provides the inductor current return path. The non-synchronous architecture trades slightly lower efficiency at light loads for simplicity and lower cost (no low-side MOSFET). The controller uses peak current-mode control where the PWM comparator compares the current sense signal with the error amplifier output to set the duty cycle. (2) The switching frequency is set by an external resistor from the RT\/CLK pin to GND, adjustable from 100kHz to 2.2MHz. Higher frequencies allow smaller inductors and capacitors but increase switching losses. The RT\/CLK pin also accepts an external clock for synchronization. The B version adds spread-spectrum frequency dithering (approximately +\/-10% modulation) that spreads the switching energy across a wider bandwidth, reducing peak EMI emissions. (3) The 60V maximum input voltage makes the device suitable for automotive (12V\/24V battery with load dump transients) and industrial (24V\/48V rails) applications. The 6.5A minimum current limit ensures 5A output current delivery even at low input voltages. The external compensation allows optimization for various output capacitor types and values, enabling design flexibility not available with internally compensated devices.","pin_description":"
