APE1913

Advanced Power Electronics Corp. FEATURES Input Voltage：2.6V to 5.5V Adjustable Output Voltage Range up to 27V 1.2MHz Fixed Switching Frequency Internal Soft-Start Function Current Limit and Thermal Shutdown Protection Under Voltage Lockout < 1µA Shutdown Current Available in the TSOT-23-5L Package APE1913 DESCRIPTION The APE1913 is a current mode step up converter intended for small, low power applications. The converter input voltage ranging from 2.6V to 5.5V. The Output voltage can be set up to 27V. The frequency is 1.2MHz allows the use of small external inductors and capacitors and provides fast transient response. Internal soft start results in small inrush current and extends battery life. Internal power MOSFET with very low RDS (ON) provides high efficiency. The APE1913 automatically transits from PWM to PFM during light load condition further increasing efficiency. The converter also provides protection functions such as under-voltage lockout, current limit and thermal shutdown. The APE1913 is available in TSOT-23-5L package. 1.2MHz, HIGH VOLTAGE, BOOST CONVERTER TYPICAL APPLICATION VIN=5V L1 4.7uH U1 VCC EN OFF C3 1nF GND APE1913 SW FB R3 R1 54K D1 B240A VOUT=12V ON C1 10uF R4 1M R2 470K C2 4.7uF R2 VOUT = 1.238V X (1 + ------- ) R1 R2 Suggest 390K~820K VIN 2.6~3.6V 2.6~5.3V 2.6~5.5V VOUT 5V 7V 7.5~27V R3 120KΩ 82KΩ 0Ω PACKAGE & ORDERING INFORMATION (Top View) APE1913X Package Type TY5 : TSOT-23-5L SW GND FB 1 2 3 5 VCC 4 TSOT-23-5L EN Data and sp...
