MAX608 - 5V or Adjustable / Low-Voltage / Step-Up DC-DC Controller

General Description

The MAX608 low-voltage step-up controller operates from a 1.8V to 16.5V input voltage range.

Pulse-frequency-modulation (PFM) control provides high efficiency at heavy loads, while using only 85µA (typical) when operating with no load.

Key Features
