Semtech Expands Broad Platform of POL Regulators with Easy-to-Use, 4A Device
Semtech has expanded its point-of-load (POL) regulator platform to include a highly-integrated, 4A output current, synchronous buck regulator with programmable soft-start in a tiny 3 x 3 x 0.6mm package. The new SC185 joins Semtech’s existing platform of POL regulators, which includes a wide selection of output currents ranging from 0.5A to 4A.
Maxim's LED solution enables drop-in replacements for halogen MR16 lamps
Maxim introduced the MAX16840, an LED driver that employs a proprietary architecture to ensure flicker-free, dimmable operation with electronic transformers and cut-angle dimmers. Maxim’s patent-pending approach enables the design of retrofit LED lamps that can replace halogen MR16s without any changes to the existing electrical infrastructure. This removes an important obstacle to commercial viability, allowing end users to enjoy all the benef...
MAX16838: Maxim releases the first two-string HB LED driver for automotive applications
Maxim introduced the MAX16838, the industry's only two-string HB (high-brightness) LED driver for automotive applications. This device integrates a boost or SEPIC switching converter, two linear current sinks, and all necessary power MOSFETs. The MAX16838 is able to optimize conversion efficiency, provide complete fault protection, and allow a 5000:1 dimming range-without any external components. This HB LED driver is well suited for LCD backligh...
Highly integrated IEEE 802.3af/at-compliant PSE controller delivers up to 40W and saves space and cost in PoE+ powered devices
Maxim introduced the MAX5971B, a single-port power-sourcing equipment (PSE) controller for IEEE(R) 802.3af/at-compliant, high-power power-over-Ethernet (PoE+) applications. This device integrates a 0.5ohm power MOSFET, sense resistor, and current monitor to save space and cost in PSE systems--the typical application circuit requires fewer than eight external components. Additionally, the MAX5971B includes a 9-bit ADC and I2C interface to enable a...
Battery Switch has Four Enable Inputs for Disconnecting a Li+ Battery from a Load in Portable Applications
Maxim Integrated Products has introduced the MAX14525 battery switch with four enable inputs. Optimized for disconnecting a lithium-ion battery from its load, this device features a low, 35milliohm (typ) Ron and an ultra-low, 0.8microamp (typ) quiescent supply current. The MAX14525 integrates all necessary components (a comparator, logic, MOSFET, etc.) and eliminates up to eight additional components with its four unique control inputs. Packaged ...
