LM2594HV Datasheet | Texas Instruments

Features - 1 New product available: LMR36506 3-V to 65-V 0.6-A ultra-small synchronous buck converter - 3.3-V, 5-V, 12-V, and adjustable output versions - Adjustable version output voltage range: 1.2 V to 37 V (57-V for the HV version), ±4% maximum over line and load conditions - Available in 8-pin surface-mount SOIC and 8-pin PDIP packages - Ensured 0.5-A output current - Input voltage range up to 60 V - Requires only four external ponents - 150-k Hz Fixed-frequency internal oscillator - TTL shutdown capability - Low power standby mode, IQ typically 85 μA - High efficiency - Uses readily-available standard inductors - Thermal shutdown and current-limit protection - Start WEBENCH design with LM2594HV 2 Applications - Simple high-efficiency step-down (buck) regulator - Efficient preregulator for linear regulators - On-card switching regulators - Positive-to-negative convertor 3 Description The LM2594xx series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 0.5-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version, and are packaged in a 8-pin PDIP and a 8pin surface-mount SOIC package. Requiring a minimum number of external ponents, these regulators are simple to use and feature internal frequency pensation, a fixedfrequency oscillator, and improved line and load regulation specifications. The new product, LMR36506, offers reduced BOM cost, higher efficiency, and smaller solution size with many other features . See the Device parison Table to pare specs.
