21 / 74 page  PAC5255 Power Application Controller 10. MULTI-MODE POWER MANAGER (MMPM) 10.1. Features Multi-mode switching supply controller configurable as high voltage or ultra-high-voltage buck, flyback AC/DC DC supply up to 52V or line AC input 4 linear regulators with power and hibernate management Power and temperature monitor, warning, and fault detection 10.2. Block Diagram 10.3. Functional Description The Multi-Mode Power Manager (Figure 10-1) is optimized to efficiently provide "all-in-one" power management required by the PAC and associated application circuitry from a wide range of input power sources. It incorporates a dedicated multi- mode switching supply (MMSS) controller operable as a buck, flyback, or boost converter to efficiently convert power from a DC or AC input source to generate a main supply output VP. Four linear regulators provide VSYS, VCCIO, VCC33, and VCC18 supplies for 5V system, 5V or 3.3V I/O, 3.3V mixed signal, and 1.8V microcontroller core circuitry. The power manager also handles system functions including internal reference generation, timers, hibernate mode management, and power and temperature monitoring. 10.3.1. Multi-Mode Switching Supply (MMSS) Controller The MMSS controller drives an external power transistor for pulse-width modulation switching of an inductor or transformer for power conversion. The DRM output drives the gate of the n-channel MOSFET or the base of the NPN between the VHM on state and VSSP off state at proper duty cycle and switching frequency to ensure that the main supply voltage VP is regulated. The VP regulation voltage is initially set to 15V during start up, and can be reconfigured to be 12V - 21 - Rev 1.10‒March 3, 2018 Figure 10-1.
