Tps63051rmwr voltage rise and fall DC-DC power chip inventory clearing and sale
explain
Tps6305x series devices are high-efficiency buck / boost converters with low quiescent current, which are suitable for applications where the input voltage is higher or lower than the output voltage. In the boost mode, the continuous output current can reach up to 500mA; In step-down mode, the continuous output can be up to 1a. The maximum average switching current is limited to 1a (typical).
Tps6305x series devices conduct voltage stabilizing operation for the output voltage within the whole input voltage range, and can automatically switch to step-down or step-up mode according to the input voltage, so as to realize seamless conversion between the two modes. The buck / boost converter is based on a fixed frequency PWM controller using synchronous rectification, which can achieve the highest efficiency. When the load current is low, the converter enters the energy-saving mode, so as to maintain high efficiency in the whole load current range. The user can select automatic PFM / PWM working mode or forced PWM working mode through pulse frequency modulation (PFM) / PWM pin. In PWM mode, a fixed frequency of 2.5MHz is usually used. Using an external resistance voltage divider, the output voltage can be programmed or internally fixed on the chip. The converter can be disabled to minimize battery consumption. During shutdown, the load is disconnected from the battery. The device is packaged in 12 pin chip size spherical pin grid array (dsbga) and 12 pin hotrod.
