LR2596

LESHAN RADIO COMPANY, LTD. LR2596 150KHz, 3A PWM Buck DC/DC Converter LR2596 Series TO220-5L Package TO263-5L Package Description The LR2596 is Monolithic IC that design for a step-down DC/DC Converter, and own the ability of driving a 3A load without additional transistor component. The output version included 3.3V, 5V, 12V and an adjustable type. It operates at a switching frequency of 150KHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Other features include a guaranteed ±4% tolerance on output voltage under specified input voltage and output load conditions, and ±15% on the oscillator frequency. Regarding protected function, thermal shutdown is to prevent over temperature operating from damage, and current limit is against over current operating of the output switch. Features 3.3V, 5V, 12V and adjustable Adjustable version output voltage range: 1.4-37V ±4% max over line and load conditions 150KHz ±15% fixed switching frequency TTL shutdown capability Operating voltage can be up to 40V Output load current: 3A TO220-5L and TO263-5L packages Low power standby mode Thermal-shuntdown and current-limit protection High efficiency Built-in switching a transistor on chip, requires only 4 external components Applications Simple High-efficiency step-down regulator Positive to negative converter On-card switching regulators Connection Diagrams Side View TO220-5L Top View Metal ...
