DATASHEET ISL8212M FN8990 Rev.1.00 15A High Efficiency Step-Down Power Module Feb 15, 2019 The ISL8212M power module is a single channel, Features synchronous step-down, non-isolated complete power R4 Technology supply featuring the proprietary Renesas R4 Linear control loop for optimal transient response Technology. The module supports a wide 4.5V to 16.5V input voltage range and a wide 0.5V to 5V output range Variable frequency and duty cycle control during capable of delivering up to 15A of continuous current, load transient for fastest possible response and is optimized for high power density. Integrated Inherent voltage feed-forward for wide range LDOs provide module bias voltage, allowing for single input supply operation. Input voltage range: 4.5V to 16.5V The proprietary Renesas R4 control scheme has extremely fast transient performance, accurately Output voltage range: 0.5V to 5V regulated frequency control, and all internal 1.5% load and line regulation with remote sense compensation. An efficiency enhancing PFM mode Supports all ceramic solutions greatly improves light-load efficiency. The ISL8212M allows for easy R4 loop optimization, resulting in fast Integrated LDOs for single input rail solution transient performance across a wide range of 256 output voltage levels with a configuration pin applications, including all ceramic output filters. Seven switching frequency options from 300kHz to The power module integrates all power and most passive 1MHz components and requires only a few external components to operate. A set of optional external resistors provides PFM operation option for improved light-load very flexible configuration options (such as frequency, efficiency V , and AV gain). The ISL8212M also features remote OUT Start-up into precharged load voltage sensing and completely eliminates any potential Power-good monitor for soft-start and fault detection difference between remote and local grounds, improving regulation and protection accuracy. A programmable Comprehensive fault protection for high system soft-start reduces the inrush current from the input reliability supply. A precision enable input and power-good Over-temperature protection (PGOOD) flag are available to coordinate the start-up of the ISL8212M with other voltage rails, which is Output overcurrent and short-circuit protection especially useful for power sequencing. Excellent Output overvoltage and undervoltage protection efficiency and low thermal resistance permit full power operation without heatsinks. Open remote sense protection Input Undervoltage Lockout (UVLO), over-temperature, Input UVLO and power sequence as well as fault overcurrent, output overvoltage, and output prebias reset start-up protections ensure safe operations under Thermally enhanced 12mmx11mmx5.3mm HDA abnormal operating conditions. package The ISL8212M is available in a compact RoHS Related Literature compliant thermally-enhanced 12mmx11mmx5.3mm For a full list of related documents, visit our website: HDA package.
