MAX8627ETD+T

The MAX8627ETD+T is a low VBATT, 20µA IQ, 1MHz synchronous boost converter with true shutdown in 14 pin TDFN package. The step-up converter is a high efficiency, low-quiescent current and inrush current limiting. IC generates any boosted output voltage from 3V to 5V from a 2-cell NiMH/NiCd or a single-cell Li+/Li polymer battery. Quiescent current is only 20µA (typ) and at light loads converter pulses only as needed for best efficiency. At higher loads, PWM mode maintains fixed 1MHz operation for lowest noise and ripple. It includes an internal soft-start to limit inrush current to a maximum of 500mA. Additional features include True Shutdown, internal compensation and adjustable current limit. It is used in DSC motors and backup power, microprocessor/DSP core power and cell phones, PDAs, MP3 players.

• Operating input voltage range from 0.9V to 5.5V
• Operating temperature range from 40°C to +85°C
• True shutdown output
• Up to 95% efficiency
• Output current of 1A
• Soft start eliminates inrush current
• Quiescent current of 20µA (typ)
• Logic controlled shutdown is 0.1µA
• Internal synchronous rectifier, low noise antiringing feature
• Internal compensation, adjustable current limit
