产品详情
The MAX20071/MAX20072 high-efficiency switching regulator family delivers up to a 1A load current from 0.5V to 3.8V. The device operates from an input voltage range of 3.0V to 5.5V making it ideal for on-board point-of-load and post-regulation applications. Total output error is less than ±1.5% over load, line, and temperature.
The MAX20071/MAX20072 features fixed-frequency PWM mode operation with a switching frequency of 2.2MHz. High-frequency operation enables an all-ceramic capacitor design and small external components.
The MAX20071/MAX20072 provides an enable input and PGOOD output. The output voltage can be preset at the factory to allow customers to achieve ±1.5% output- voltage accuracy without external 0.1% resistors. In addition, the output voltage can be set to any customer value by using two external resistors at the feedback with 0.5V internal reference. The devices offers a fixed 0.85ms soft-start time.
The 8-pin TDFN exposed pad devices include overtemperature shutdown and overcurrent limiting. All devices are designed to operate from -40°C to +125°C ambient temperature.
