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.

MAX17499AAUB+ General Description

The MAX17499/MAX17500 current-mode PWM con-trollers contain all the control circuitry required for thedesign of wide-input-voltage isolated and nonisolatedpower supplies. The MAX17499 is well suited for lowinput voltage (9.5V DC to 24V DC) power supplies. TheMAX17500 is well suited for universal input (rectified85V AC to 265V AC) or telecom (-36V DC to -72V DC)power supplies.The ICs contain an internal error amplifier that regulatesthe tertiary winding output voltage that is used in prima-ry-side-regulated isolated power supplies. Primary-sideregulation eliminates the need for an optocoupler. Aninput undervoltage lockout (UVLO) is provided for pro-gramming the input-supply start voltage and to ensureproper operation during brownout conditions. An open-drain UVLO flag output, with 210μs internal delay,allows the sequencing of a secondary-side controller.The input-supply start voltage is externally programma-ble with a voltage-divider. A UVLO/EN input is used toshut down the devices. Internal digital soft-start elimi-nates output voltage overshoot.The MAX17500 has an internal bootstrap UVLO withlarge hysteresis that requires a minimum 23.6V for start-up. The MAX17499 does not have the internal bootstrapUVLO and can be biased directly from a minimum volt-age of 9.5V.The switching frequency for the ICs is programmablewith an external resistor. The MAX17499A/MAX17500Aprovide a 50% maximum duty-cycle limit, while theMAX17499B/MAX17500B provide a 75% maximumduty-cycle limit. These devices are available in 10-pinμMAX® packages and are rated for operation over the-40°C to +125°C temperature range.
