Description

DC/DC CONV BUCK 127KHZ TQFN-16
The MAX5090A/B/C easy-to-use, high-efficiency, high- voltage step-down DC-DC converters operate from an input voltage up to 76V, and consume only 310µA quiescent current at no load. This pulse-width-modulated (PWM) converter operates at a fixed 127kHz switching frequency at heavy loads, and automatically switches to pulse-skipping mode to provide low quiescent current and high efficiency at light loads. The MAX5090 includes internal frequency compensation simplifying circuit implementation. The device can also be synchronized with external system clock frequency in a noise-sensitive application. The MAX5090 uses an internal low on-resistance and a high-voltage DMOS transistor to obtain high efficiency and reduce overall system cost. This device includes undervoltage lockout, cycle- by-cycle current limit, hiccup-mode output short-circuit protection, and overtemperature shutdown. The MAX5090 delivers up to 2A output current. External shutdown is included, featuring 19µA (typ) shutdown current. The MAX5090A/MAX5090B versions have fixed output voltages of 3.3V and 5V, respectively, while the MAX5090C features an adjustable 1.265V to 11V output voltage. The MAX5090 is available in a space-saving 16-pin thin QFN package (5mm x 5mm) and operates over the automotive temperature range (-40°C to +125°C).
