MAX618EEE+

The MAX618EEE+ is a CMOS, PWM, Step-up DC-DC Converter generates output voltages up to 28V and accepts inputs from +3 to +28V. An internal 2A, 0.3Ω switch eliminates the need for external power MOSFETs while supplying output currents up to 500mA or more. A PWM control scheme combined with Idle Mode™ operation at light loads minimizes noise and ripple while maximizing efficiency over a wide load range. No-load operating current is 500µA, which allows efficiency up to 93%. A fast 250kHz switching frequency allows the use of small surface-mount inductors and capacitors. A shutdown mode extends battery life when the device is not in use. Adaptive slope compensation allows the MAX618 to accommodate a wide range of input and output voltages with a simple, single compensation capacitor.

• Up to 93% efficiency
• Up to 500mA output current at +12V
• 500µA Quiescent supply current
• 3µA Shutdown current
