Product Description

This item is the D30V33MASCMA, which has an adjustable output voltage (4.2 V to 15 V) and an adjustable low-voltage cutoff.

The D30V3x line of synchronous buck (step-down) voltage regulators generates lower output voltages from input voltages as high as 45 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters), which makes them much more efficient than linear voltage regulators, especially when the difference between the input and output voltage is large. These regulators can typically support continuous output currents between 1 A and 4 A, depending on the input voltage and output voltage. In general, the available output current decreases as the input and output voltages increase.

This line consists of the D30V30Fx family of fixed output voltages ranging from 3.3 V to 15 V and two families of adjustable versions that allow the output voltage to be set with a precision 11-turn potentiometer. Each adjustable option is available with or without an adjustable low-voltage cutoff (also set through a precision 11-turn potentiometer on the versions that have it). The adjustable families are the D30V30MAx, which is the more compact of the two thanks to its double-sided assembly, and the D30V33MAx, which includes larger through-holes for terminal blocks and can do slightly more current thanks to its larger surface area.

Features

Input voltage: VOUT to 45 V (input must be higher than the output voltage and is subject to dropout voltage considerations; see the dropout voltage section for details)
Output voltage: 4.2 V to 15 V (precision-adjustable using built-in 11-turn potentiometer)
Typical maximum continuous output current: 1.3 A to 4.3 A (see the maximum continuous output current graph below)
Configurable low-voltage cutoff threshold (precision-adjustable using built-in 11-turn potentiometer)
Typical efficiency of 80% to 95%, depending on input voltage, output voltage, and load (see the efficiency graphs below)
Very low dropout voltage
Switching frequency: ~700 kHz under heavy loads
Power-save mode that increases light load efficiency by reducing switching frequency
Low quiescent current (see the quiescent current graph below)
Enable input for disconnecting the load and putting the regulator into a low-power shutdown state
“Power good” output indicates when the regulator cannot adequately maintain the output voltage
Frequency spread spectrum operation that lowers peak EMI noise
Under-voltage lockout protection
Soft-start feature limits inrush current and gradually ramps output voltage
Integrated reverse-voltage protection up to 40 V, over-current and short-circuit protection, over-temperature shutoff
Two 0.086″ mounting holes for #2 or M2 screws
Through-holes for 0.1″ headers as well as for 3.5mm-pitch terminal blocks

Dimensions (Without included optional connectors)

Size: 0.9″ x 1.2″ x 0.3″(22.9 mm x 30.5 mm x 7.7 mm).
Weight: 4.7 g

General specifications

Minimum operating voltage: 4.2 V. Operating voltage must be higher than the set output voltage and is subject to dropout voltage considerations.
Maximum operating voltage: 45 V
Minimum output voltage: 4.2 V. Output voltage is set by a built-in precision 11-turn potentiometer.
Maximum output voltage: 15 V
Continuous output current: 3.3 A. Typical maximum continuous output current at 30 V in and 9 V out. Actual achievable continuous output current is a function of input and output voltages and is limited by thermal dissipation
Reverse voltage protection?: Y. To -40 V. Connecting supplies over 40 V in reverse can damage the device.
Maximum quiescent current: 20 mA. While enabled with no load. The quiescent current is a function of the input voltage, output voltage, and cutoff voltage. It is reduced to under 1 mA at higher input voltages and with correspondingly higher cutoff voltage settings or when the regulator is disabled via the enable pin.
Low-voltage cutoff: adjustable
Output type: adjustable 4.2V-15V
