NCV97310MW33GEVB: Multi-output Power Management Unit (PMU) with 3 Buck Regulators Evaluation Board

Evaluation board for the NCV97310 3-output regulator consisting of a low-Iq battery-connected 3 A 2 MHz non-synchronous switcher and two low-voltage 1.5 A 2 MHz synchronous switchers; all using integrated power transistors. The high-voltage switcher is capable of converting a 4.1 V to 18 V battery input to a 5 V or 3.3 V output at a constant 2 MHz switching frequency, delivering up to 3 A. In overvoltage conditions up to 36 V, the switching frequency folds back to 1 MHz; in load dump conditions up to 45 V the regulator shuts down. The output of the battery-connected buck regulator serves as the low voltage input for the 2 synchronous switchers. Each downstream output is adjustable from 1.2 V to 3.3 V, with a 1.5 A current limit and a constant 2 MHz switching frequency. Each switcher has independent enable and reset pins, giving extra power management flexibility. For low-Iq operating mode the low-voltage switchers are disabled, and the standby rail is supplied by a low-Iq LDO (up to 150 mA) with a typical Iq of 30 µA. The LDO regulator is in parallel to the high-voltage switcher, and is activated when the switcher is forced in standby mode. All 3 SMPS outputs use peak current mode control with internal slope compensation, internally-set soft-start, battery undervoltage lockout, battery overvoltage protection, cycle-by-cycle current limiting, hiccup mode short-circuit protection and thermal shutdown. An error flag is available for diagnostics.
