L5963 Dual Monolithic Switching Regulator Evaluation Board

Dual monolithic switching regulator with LDO and HSD ? Two step-down synchronous switching voltage regulators with internal power switches: – Wide input voltage range (from 3.5 V to 26 V) – Internal high-side/ low-side NDMOS – 1 V minimum output – 3.0 A load current – 250 kHz free-run frequency – 250 kHz < f < 2 MHz synchronization range – Integrated soft-start – Independent hardware enable pins – Independent power supply – 180° PWM output phase shift – Programmable switching frequency divider by 1, 2, 4 or 8 between the two DC/DC regulators – Power good function ? One standby / linear regulator – Output voltage programmable with external resistor divider – 250 mA maximum current capability – Backup function – Power good function ? One high side driver – 0.5 V max drop @ 0.5 A – Protected against short to ground and battery, loss of ground and battery, unsupplied short to battery ? Programmable under voltage battery detector – Under voltage threshold adjustable through dedicated pin (VDIN) ? Load dump protection ? Independent thermal protection on all regulators ? Independent current limit on all regulators
