DescriptionThe MIC2182BM is one member of the MIC2182 family which designed as the synchronous buck (step-down) switching regulator controller, MIC2182BM can be used in (1)dc power distribution systems; (2)notebook and subnotebook computers; (3)PDAs and mobile communicators; (4)wireless modems; (5)battery-operat-ed equipment. The operating mode of this device is internally selected according to the output load conditions. Skip mode can be defeated by pulling the PWM pin low which reduces noise and RF interference.
Features of the MIC2182BM are:(1)20A output current capability;(2)sustained short-circuit protection at any input voltage;(3)frequency foldback overcurrent protection;(4)16-pin SOP and SSOP packages;(5)0.6% total regulation;(6)precision 1.245V reference output;(7)easily synchronizable;(8)adjustable under-voltage lockout;(9)built-in undervoltage protection;(10)cycle-by-cycle current limiting;(11)drives N-channel MOSFETs;(12)600A typical quiescent current (skip-mode);(13)current-mode control;(14)current sense blanking;(15)5 impedance MOSFET Drivers.
The absolute maximum ratings of the MIC2182BM can be summarized as:(1)analog supply voltage (VIN):+34 V;(2)digital supply voltage (VDD):+7 V;(3)driver supply voltage:VIN +7V;(4)sense voltage:7V to -0.3V;(5)sync pin voltage:7V to -0.3V;(6)ambient storage temperature:-65°C to +150°C.
