Allegro MicroSystems Inc. 40V Input, 2.6A/2Mhz Sr Buck W/Cable Drop Comp A8653KLPTR-T

Description
The A8652/53 is a high output current synchronous Buck regulator that provides tight load regulation over a wiring harness without the need for remote sense lines. This remote load regulation is achieved with an integrated open-loop correction scheme that, given a known wiring harness resistance, adjusts the output voltage based on the measured load current and a user programmable gain, achieving ±2% accuracy at 500 mV of correction. The Remote Load Regulation control includes a 115% regulated voltage clamp in conjunction with a dynamic over voltage protection with OVP threshold changing with the correction voltage. The A8652/53 includes a user configurable load side current limit to fold back the output voltage during an output over current condition. The A8652/53 regulates nominal input voltages from 4.0 V to 36 V and remains operational when VIN drops as low as 2.6 V. When the input voltage approaches the output voltage, the duty cycle is maximized to maintain the output voltage. The A8652/53’s features include externally set soft-start time, external compensation network, an EN input to enable VOUT, a SYNC/FSET input to synchronize or set the PWM switching frequency, and a PowerOK output to indicate when VOUT is within regulation and there is no load side current limit condition. Protection features include VIN under-voltage-lockou t, cycle-by-cycle current limit, hiccup mode short-circuit protection, dynamic over-voltage protection, and thermal shutdown. A8652/53 provides open-circuited, adjacent pin short-circuit, and short-to-ground protection at every pin to satisfy the most demanding automotive and non-automotive applications. The A8652/53 device is available in a 16-pin eTSSOP package with exposed pads for enhanced thermal dissipation. It is lead (Pb) free, with 100% matte tin lead frame plating. The maximum junction temperature (TJ(max)) is 150°C.
