DC-DC regulator range from Nu Horizons maximises available board space
Nu Horizons announces the availability of a range of point of load DC-DC regulators. Linear Technology's new generation of POL regulator modules include all the circuit components encapsulated in such a tiny size that they resemble a surface mount IC. These high-end point-of-load regulators are complete solutions containing the DC-DC controller, MOSFETs, inductor, input and output bypass capacitors and compensation circuitry in only 225mm2, maximising available board space. The single package regulator range also improves electrical and thermal performance.
ProdThe LTM4607 is a high efficiency buck-boost DC-DC module with wide Vin (4.5 to 36V) and Vout (0.8 to 2V) ranges. It can produce 5A DC (10A DC in buck mode) and has a high efficiency of up to 98%. Features include current mode control, a power output good signal, ultra-fast transient response and output overvoltage protection. It comes in a small, low profile surface mount LGA package measuring 15 by 15 by 2.8mm.
The LTM4604 is a complete standalone power supply with a wide input voltage range of 2.375 to 5.5V, and output range of 0.8 to 5V. Peak output current is 5A and the module features output voltage tracking. Ultra-fast transient response, a power good indicator, programmable soft-start and micropower shutdown are included in a tiny low-profile package measuring 15 by 9 by 2.3mm.
All μModules are overmolded in a solid array and individual units are saw singulated. μModule components are leadless with electrical connections being made through the land pad array.
