Aimtec expands its switching regulator converter product line with the addition of the AMSR1-78-NZ series of non-isolated, DC-DC switching regulators.
A feature rich, pin-to-pin replacement of 78xx linear regulators, the AMSR1-78-NZ step-down converters provide highly regulated output voltages ranging from 3.3VDC to 12VDC, producing maximum output currents of 1A at efficiency rates of up to 96% that remain virtually constant over the entire input range. Low output ripple and noise (60mV p-p) make these robust converters ideal for noise sensitive applications.
Ultra wide input ranges (up to 6:1) extend from 4.75-32VDC to 16-33VDC allowing these highly reliable products to be powered from unregulated sources.
Designed in a SIP3 package (11.68 x 8.9 x 17.5mm), the AMSR1-78-NZ series is pin compatible to the TO-220 package and makes these power supplies ideal for low profile circuit implementations such as portable power and standby-power applications.
Versatile for a multitude of industrial applications, the AMSR1-78-NZ series is designed to operate at full output power without heatsinking or forced-air cooling below +85°C, which is a distinct advantage for all applications.
Useful features include continuous short circuit protection, output current limit and thermal shutdown, Aimtec’s AMSR1-78-NZ series of DC-DC switching regulator converters can operate continuously at full load without the need for load derating below +71° C, within an ambient temperature range of -40° to +85°C.
The AMSR1-78-NZ series is made with high quality, RoHS compliant materials that undergo rigorous quality control to ensure reliability and performance.

Part: IR3624M
Description: High Frequency Synchronous PWM Buck Controller in a 10-Lead MLPD Package.
Features
* Internal 600kHz Oscillator
* Operates with Single 5V or 12V Supply
* Programmable Over Current Protection
* Hiccup Current Limit Using MOSFET RDS(on) sensing
* Precision Reference Voltage (0.6V)
* Programmable Soft-Start
* Pre-Bias Start-up
* Thermal Protection
* 10-Lead MLPD Package
The IR3624 is a PWM controller designed for high performance synchronous Buck DC/DC applications. The IR3624 drives a pair of external N-MOSFETs using a fixed 600kHz switching frequency allowing the use of small external components. The output voltage can be precisely regulated using the internal 0.6V reference voltage for low voltage applications. Protection such as Pre-Bias startup, hiccup current limit and thermal shutdown are provided to give required system level security in the event of fault conditions.
