See http://www.bookly.com for more information about Bookly Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green” p ducts are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) ro and <1000ppm antimony compounds. Notes: Simple High-Efficiency Step-Down Regulator On-Card Switching Regulators Positive to Negative Converter • • • Applications Halogen and Antimony Free. “Green” Device (Note 3) Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) • Operating Voltage can be up to 36V max. Output Load Current: 3A Low Power Standby Mode Built-in Switching Transistor On Chip BM1507-XXD5L-XX Totally Lead-Free; RoHS Compliant (Notes 1 & 2) BM1507-XXD5-XX ON/OFF Shutdown Control Input 150KHz +15% Fixed Switching Frequency Voltage Mode Non-Synchronous PWM Control Thermal-Shutdown and Current-Limit Protection Adjustable Version Output Voltage Range, 1.23V to 15V +4% Output Voltage: 3.3V, 5V, 12V and Adjustable Output Version • • • • • • • • • • • Features TO252-5L Metal Tab GND 5 SD 4 FB 3 GND 2 Output 1 VIN (Top View) Pin Assignments BM1507 is available in a 5-lead TO-252 lead-free or green package. version included a fixed 3.3V, 5V, 12V, and an adjustable type. load conditions, and +15% on the oscillator frequency. The output tolerance on output voltage under specified input voltage and output switching regulators. Other features include a guaranteed +4% components than what would be needed with lower frequency switching frequency of 150KHz thus allowing smaller sized filter function occurred and VFB is down to 0.5V below, the switching frequency will be reduced. The BM1507 series operates at a against over current operating of the output switch. If the current limit temperature operating from damaging the device, and current limit is line and load regulation without an external design. Regarding the protected function, the thermal shutdown is to prevent over The internal compensation makes the feedback control have good can be controlled by logic level and then come into standby mode. board space can be saved easily. The external shutdown function transistor. Due to reducing the number of external components, the converter and is capable of driving a 3A load without an external The BM1507 is a monolithic IC designed for a step-down DC/DC Description 150KHz, 3A PWM BUCK DC/DC CONVERTER BM1507 |
