| Not Recommended for New Design 150KHz, 1.5A PWM Buck DC/DC Converter AP1515 - Features - Output voltage 3.3V and adjustable output version - Adjustable version output voltage range, 1.23V to 18V+4% - 150KHz +15% fixed switching frequency - Voltage mode non-synchronous PWM control - Thermal-shutdown and current-limit protection - Operating voltage can be up to 22V - Output load current 1.5A - SIP-4L, SOP-8 Pb-Free package - Low power standby mode - Built-in switching transistor on chip - Very Low Cost - Applications - Simple High-efficiency step-down regulator - On-card switching regulators - Positive to negative converter - General Description The AP1515 series are monolithic IC designed for a step-down DC/DC converter, and own the ability of driving a 1.5A load without additional transistor component. Due to reducing the number of external component, the board space can be saved easily. The external shutdown function can be controlled by logic level and then come into standby mode. The internal compensation 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. If current limit function occurred and VFB is down to 0.5V below, the switching frequency will be reduced. The AP1515 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 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 and an adjustable type. - Pin Assignments - Pin Descriptions 1515 Front View 1 VIN 2 Output 4 GND 12 3 4 SIP-4L VIN Output FB SD Top View SOP-8L Name VIN Output FB SD GND Description Operating voltage input Switching output voltage feedback control ON/OFF Shutdown Ground This datasheet contains new product information.
