DC-DC преобразователи интегральные LM2599S-5.0/NOPB

Понижающий импульсный стабилизатор , фиксированный, 4.5В-40В (Vin), 5В и 3A на выходе, TO-263-7

The LM2599S-5.0/NOPB is a step-down Voltage Regulator provides all the active functions for a step-down (buck) switching regulator, capable of driving a 3A load with excellent line and load regulation. It requires a minimum number of external components, it is simple to use and include internal frequency compensation, improved line and load specifications, fixed-frequency oscillator, shutdown and soft-start, error flag delay and error flag output. The LM2599 series 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 ±4% tolerance on output voltage under all conditions of input voltage and output load conditions and ±15% on the oscillator frequency. External shutdown is included, featuring typically 80-µA standby current. Self-protection features include a two stage current limit for the output switch and an overtemperature shutdown.

• Out-of-regulation error flag
