• High efficient next generation microcontroller power supply system
• Wide battery input voltage range < 4.5 V up to 45 V
• Operating temperature range Tj = -40 °C to +150 °C
• Pre-regulator for low all over power loss:
Integrated current mode *** converter 5.5 V/2.5 A
• Post-regulators, e.g. for system and controller I/O supply:
– LDO1: 5V &plu***n;2%, 800 mA current limit
– LDO2: 3.3 V &plu***n;2% or 2.6V &plu***n;2% (selectable output), 700 mA
current limit
• Integrated linear regulator control circuit to supply controller cores:
– LDO3 control for an external NPN power stage:
– 1.5V &plu***n;2% at TLE7368G and TLE7368E

• Post-regulators for off board supply:
– 2 Tracking regulators following the main 5 V, 105 mA and 50 mA
• Stand-by regulator with lowest current c***umption:
– Linear voltage regulator as stand-by supply for e.g.
memory circuits
– Ha***are selectable output voltages as 1.0 V or 2.6 V, 30 mA
– Independent battery input, separated from *** regulator input
• Ha***are controlled on/off logic
