What is the Surface Mount ?

having leads that are designed to be soldered on the side of a circuit board that the body of the component is mounted on.

What is the Operating Temperature ?

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

What is the Packaging ?

Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.

What is the Part Status ?

Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.

What is the Terminal Form ?

Occurring at or forming the end of a series, succession, or the like; closing; concluding.

What is the Terminal Pitch ?

The center distance from one pole to the next.

What is the Max Supply Voltage ?

In general, the absolute maximum common-mode voltage is VEE-0.3V and VCC+0.3V, but for products without a protection element at the VCC side, voltages up to the absolute maximum rated supply voltage (i.e. VEE+36V) can be supplied, regardless of supply voltage.

What is the Min Supply Voltage ?

The minimum supply voltage (V min ) is explored for sequential logic circuits by statistically simulating the impact of within-die process variations and gate-dielectric soft breakdown on data retention and hold time.

What is the Nominal Supply Current ?

Nominal current is the same as the rated current. It is the current drawn by the motor while delivering rated mechanical output at its shaft.

What is the Quiescent Current ?

The quiescent current is defined as the current level in the amplifier when it is producing an output of zero.

What is the Synchronous Rectifier ?

Synchronous rectification is a technique for improving the efficiency of rectification by replacing diodes with actively controlled switches, usually power MOSFETs or power bipolar junction transistors (BJT).

What is the RoHS Status ?

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.

The MAX15157ATJ+ constant-off-time, pulse-width-modulated (PWM) source/sink step-down DC-DC converter is optimized for use in low-voltage active-termination power rails or chipset power supplies in notebook and sub-notebook computers. This device features dual internal n-channel MOSFET power switches for high efficiency and reduced component count. External Schottky diodes are not required. An integrated boost switch eliminates the need for an external boost diode. The internal 40mΩ NMOS power switches easily source and sink continuous load currents up to 3A. The MAX15157ATJ+ produces an adjustable output from +0.5V to +2.7V and achieves efficiencies as high as 95%.

The MAX15157ATJ+ can be configured as a DDR regulator, producing an output that is exactly half the memory supply rail. The input of the power stage can be taken from the memory supply rail itself, resulting in an efficient power supply that returns the energy to the rail from which it was sourced. The MAX15157ATJ+ includes a reference buffer that provides ±5mA of drive current.

The MAX15157ATJ+ uses a unique current-mode, constant-off-time, PWM control scheme. A selectable pulse-skipping mode maintains high efficiency during light-load operation, yet still sources and sinks current on demand. The MAX15157ATJ+ can also be operated in fixed-PWM mode for low output ripple. The programmable constant-off-time architecture sets switching frequencies up to 1MHz, which allows the user to optimize performance trade-offs between efficiency, output switching noise, component size, and cost. The MAX15157ATJ+ features an adjustable soft-start to limit surge currents during startup and a low-power shutdown mode to disconnect the input from the output and reduce supply current below 1μA. The MAX15157ATJ+ is available in a 24-pin thin QFN package with an exposed backside pad.
