Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.
Note 2: The AMC3100 is guaranteed to meet performance specifications from 0°C to 70°C. Specifications over the 40°C to 85°C operating temperature range are assured by design, characterization and correlation with statistical process controls.
Note 3: TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formula: TJ = TA + (PD x JA).


Description

The AMC3100 is a high efficiency synchronous buck DC/DC converter using a constant frequency, current mode architecture. Adjustable version and fixed output voltages of 1.2V, 1.5V and 1.8V are available. 300uA low supply current at no load and <1A supply current at shutdown. The 2.5V to 5.5V input voltage range makes the AMC3100 ideally suited for single Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. PWM pulse skipping mode operation provides very low output ripple voltage for noise sensitive applications.

Switching frequency is internally set at 1.5MHz, allowing using small surface mount inductors and capacitors. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.6V feedback reference voltage.

The AMC3100 is available in a low profile (1mm) Thin SOT-23-5L package.
