带旁路的超低 IQ 升降压稳压器评估板
ISL9122AIIN-EVZ 平台可对 WLCSP 封装的 ISL9122A 超低 IQ 升降压稳压器的高性能功能进行快速评估。ISL9122A 是高度集成的非反相升降压开关稳压器,可输入高于或低于调节输出电压的输入电压。该稳压器可在升降压模式间自动转换且没有显著的输出干扰。此外,它还具有极低的静态电流消耗、卓越的效率和 I2C...
The ISL9122A is a highly integrated non-inverting buck-boost switching regulator that accepts input voltages both above or below the regulated output voltage. It features an extremely low quiescent current consumption of 1300nA in Regulation mode, 120nA in Forced Bypass mode, and 8nA in Shutdown mode. It provides 84% efficiency at 10µA load (VIN = 3.6V, VOUT = 3.3V) and has a peak efficiency greater than 97%. It supports input voltages from 1.8V to 5.5V.
The ISL9122A has automatic bypass functionality for situations in which the input voltage is close to the output voltage, and it automatically transitions between Buck and Boost modes without significant output disturbance. In addition to the automatic bypass functionality, the Forced Bypass power-saving mode can be chosen if voltage regulation is not required. Forced Bypass power saving mode is accessible using the I2C interface bus.
The ISL9122A is capable of delivering up to 500mA of output current (VIN = 3.6V, VOUT = 3.3V) and provides excellent efficiency because of its adaptive frequency hysteretic control architecture.
The ISL9122A is designed for stand-alone applications and supports a default output voltage at Power-On Reset (POR). After POR, the output voltage can be adjusted in the range of 1.8V to 5.375V by using the I2C interface bus. Specific default output voltages are available on request.
The ISL9122A requires only a single EIA 0603 size inductor and two external capacitors. Power supply solution size is minimized by a 1.8mm x 1.0mm WLCSP and is also available in a 3.0mm x 2.0mm 8 Ld plastic DFN.
