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.

MAX8734AEEI+TG51 General Description

The MAX8732A/MAX8733A/MAX8734A dual step-down,switch-mode power-supply (SMPS) controllers generatelogic-supply voltages in battery-powered systems. TheMAX8732A/MAX8733A/MAX8734A include two pulse-width modulation (PWM) controllers, adjustable from 2V to5.5V or fixed at 5V and 3.3V. These devices feature twolinear regulators providing 5V and 3.3V always-on out-puts. Each linear regulator provides up to 100mA outputcurrent with automatic linear-regulator bootstrapping tothe main SMPS outputs. The MAX8732A/MAX8733A/MAX8734A include on-board power-up sequencing, apower-good (PGOOD) output, digital soft-start, and inter-nal soft-stop output discharge that prevents negative volt-ages on shutdown. Additionally, the outputs are highimpedance when VCC falls below its UVLO set point whilethe outputs are enabled.Maxim’s proprietary Quick-PWM™ quick-response, con-stant on-time PWM control scheme operates withoutsense resistors and provides 100ns response to load tran-sients while maintaining a relatively constant switching fre-quency. The unique ultrasonic pulse-skipping modemaintains the switching frequency above 25kHz, whicheliminates noise in audio applications. Other featuresinclude pulse skipping, which maximizes efficiency inlight-load applications, and fixed-frequency PWM mode,which reduces RF interference in sensitive applications.The MAX8732A features a 200kHz/5V and 300kHz/3.3VSMPS for highest efficiency, while the MAX8733A fea-tures a 400kHz/5V and 500kHz/3.3V SMPS for “thin andlight” applications. The MAX8734A provides a pin-selectable switching frequency, allowing either 200kHz/300kHz or 400kHz/500kHz operation of the 5V/3.3VSMPSs, respectively. The MAX8732A/MAX8733A/MAX8734A are available in 28-pin QSOP packages andoperate over the extended temperature range(-40°C to +85°C).The MAX8732A/MAX8733A/MAX8734A are pin-for-pinupgrades to the MAX1777/MAX1977/MAX1999.The MAX1999 evaluation kit (EV kit) can be used toevaluate the MAX8732A/MAX8733A/MAX8734A.
