16. Switching Regulators  For all step-down DC-DC voltages, I’ll be using state-of-the-art TI’s PTN78000W: a series of high-efficiency, step-down Integrated Switching Regulator (ISR). This ISR will help me to reduce system power loss significantly contrary to linear voltage regulator that has considerable loss. It features  1.5-A Output Current  Wide-Input Voltage (7 V to 36 V)  Wide-Output Voltage Adjust (2.5 V to 12.6 V)  High Efficiency (Up to 95%)  On/Off Inhibit  Output Current Limit  Overtemperature Shutdown  Operating Temp: –40°C to 85°C Mir Ziyad Ali
