GT1504 Datasheet | GMOS Technology

150Khz, 2A PWM Buck Switching Regulator - General Description The GT1504 is a monolithic integrated circuit that provide all the active functions for a step-down switching regulator, capable of driving a 2A load without additional transistor ponent. Requiring a minimum number of external ponent, the board space can be saved easily. The external shutdown function can be controlled by TTL logic level and then e into standby mode. The internal pensation makes feedback control have good line and load regulation without external design. 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. The GT1504 operates at a switching frequency of 150Khz thus allowing smaller sized filter ponents 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. The output version included fixed 3.3V, 5V, 12V, and an adjustable type. The packages are available in a standard 8-lead SOP8. 150Khz, 2A PWM Buck Switching Regulator - Ordering Information - GT1504 XX X X Output version -ADJ : Adjustable -33 : 3.3V -50 : 5.0V -12 : 12V Package BLANK: SOP-8L Packing Blank : Tube A : Taping - Features - 3.3V, 5V, 12V and adjustable output versions - Adjustable version output voltage range, 1.23V to 37V +4% max over line and load condiction - SOP-8L packages - Voltage mode non-synchronous PWM control - Thermal-shutdown and current-limit protection - ON/OFF shutdown control input - Input voltage range up to 40V - Output load current: 2A - 150 k Hz fixed frequency internal oscillator - Low power standby mode - Built-in switching transistor on chip - Applications Simple High-efficiency step-down(buck) regulator Efficient preregulator for linear regulators On-card switching...
