Buck-Boost Switching Regulator IC Positive Adjustable (Fixed) 6.5V (11.5V) 1 Output 6A 22-PowerWFQFN The MAX25239/MAX25240 are small, synchronous, buck-boost converters with integrated H-bridge switches. These ICs provide a fixed-output regulation voltage and an externally adjustable output voltage in the 3V to 20V range with an input voltage above, below, or equal to the output regulation voltage. The ICs have typical 8.2A and 10A input current limit options and can support continuous load currents up to 6A depending on the input-to-output voltage ratio and operating frequency. It also has a wide input voltage range of 2V to 36V. The MAX25239/MAX25240 have three switching frequency options: 2.1MHz, 400kHz, and 200kHz. The 2.1MHz high switching frequency allows small external components and reduced output ripple, and guarantees no AM band interference, while the 400kHz or 200kHz switching frequency offers better efficiency and relieves the power consumption concern. The SYNC input allows three operation modes: skip mode with ultra-low quiescent current, forced fixed-frequency PWM operation, and synchronization to an external clock. The IC also includes spread-spectrum frequency modulation to minimize EMI interference. The MAX25239/MAX25240 feature a power-OK (POK) indicator, undervoltage lockout, overvoltage protection, cycle-by-cycle current limit, and thermal shutdown. The ICs are available in small, 4.25mm x 4.25mm x 0.75mm, 22-pin FC2QFN and 5.00mm x 5.00mm x 0.75mm, 18- pin FCQFN packages. Key Features Wide 2 V to 36 V input voltage range Synchronous buck-boost topology for seamless step-up and step-down conversion Delivers up to 6 A continuous output current Adjustable output voltage from 3 V to 20 V (device variant includes fixed output configuration options) High conversion efficiency with integrated low-RDS(ON) MOSFETs 400 kHz switching frequency with spread-spectrum option for reduced EMI Very low 95 µA quiescent current in standby and 10 µA shutdown current Integrated protection features including overvoltage, short-circuit, thermal shutdown, and undervoltage lockout (UVLO) Power-Good (PGOOD) output for power monitoring AEC-Q100 qualified for automotive applications Operating junction temperature range: −40°C to +150°C Compact 22-pin FC2QFN (4.25 × 4.25 mm) package #MAX25240AFFFVY #AnalogDevices #BuckBoostConverter #DCDCConverter #PowerManagement #AutomotiveElectronics #AECQ100 #SwitchingRegulator #EmbeddedSystems #AutomotivePower

Battery Power Management IC Multi-Chemistry 14-TSSOP The bq34210-Q1 1-Series Cell System-Side CEDV Fuel Gauge provides fuel gauging and End-of-Service (EOS) Determination for 1-series cell batteries in applications that encounter infrequent discharge, such as eCall systems and uninterruptible power supplies (UPS) for backup during power failures, where batteries may stay connected to a charging power source most of their lifetime until needed. The bq34210-Q1 fuel gauge supports multiple battery chemistries, including Li-Ion, LiFePO4, and NiMH. The gas gauging function uses voltage, current, and temperature data along with Compensated End-ofDischarge (CEDV) technology to provide State-ofCharge (SOC) and State-of-Health (SOH) data. The device's EOS Determination function alerts when battery capability has degraded and is approaching the end of its usable service. Battery fuel gauging with the bq34210-Q1 fuel gauge requires connections only to PACK+ (P+) and PACK– (P–) for a removable battery pack or embedded battery management system.

Buck Switching Regulator IC Positive Adjustable (Fixed) 0.8V (3.3V, 5V) 1 Output 4.5A 20-WFQFN Exposed Pad The LM656x5-Q1 are a family of automotive buck converters designed for high efficiency, high-power density, and ultra-low electromagnetic interference (EMI). The converters operate over a wide input voltage range of 3V to 65V (70V transient < 100ms), reducing the need for external input surge protection. The LM656x5-Q1 comes with pin selectable fixed output voltages of 3.3V and 5V or in adjustable configuration. The low EMI operation is enabled with minimized loop inductance and optimized switch node slew rate. A pin-selectable ±5% or ±10% dual-random spread spectrum (DRSS) significantly reduces peak emissions through a combination of triangular and pseudo-random modulation while keeping output voltage ripple very low. The current-mode control architecture with a 30ns typical minimum on-time allows high conversion ratios at high frequencies coupled with a fast transient response and excellent load and line regulation.
