TPS62231TDRYRQ1-テキサス・インスツルメンツ

説明

TPS62231TDRYRQ1 sold by xt-Shenzhen is an original chip designed and developed by Texas Instruments. chip is a high-frequency, synchronous step-down DC-DC converter ideal for space-optimized automotive and industrial applications.The performance is very powerful, and the connectivity between various devices can be better reconciled. It is one of the electronic components that are in high demand in the market. If you want to know or buy more original chips, xt-Shenzhen is your good choice.

の TPS62231TDRYRQ1 supports output currents up to 500mA and allows the use of tiny, low-cost chip inductors and capacitors. Can be powered from a pre-regulated voltage rail or from a Li-Ion battery with extended voltage range. Two different fixed output voltage versions are available, 1.5 V and 1.8 Ⅴ. Switching frequency up to 3.8 MHz. The converter operates in PWM mode at medium to heavy loads and automatically enters power-saving mode operation at light load currents to maintain high efficiency over the entire load current range. Due to its excellent PSRR and AC load regulation, the device is also suitable for replacing linear regulators for better power conversion efficiency.A power save mode in the TPS62231TDRYRQ1 reduces quiescent current consumption to 22µA during light load operation. It is optimized for very low output voltage ripple, even with small external components and excellent AC load regulation.
