output voltage is 20% above or below the regular setting value. With the Over Current protection option, the designer can either select from a latched mode or fold-back version, depending on the application requirements. Latched over current protection shuts down the chip after detecting an excessive high load for a specified time and requires a reboot of the power supply to resume to normal operation after removing the excessive load. The fold-back protection circuit is triggered in a similar way but reduces the switching frequency in order to lower the excessive load current, the circuit will be released automatically after removing the excessive load. The adjustable Soft Start Time provides a smooth output voltage ramp up, by using an external capacitor. The oscillator frequency is internally fixed at 2.3MHz and the RP510 requires a small inductor of 1mH. RP510 is available in a compact 3 x 3mm DFN3030-12 package, convenient to be used on high density boards.

will also be available next month for precision sensor- signal conditioning in equipment ranging from simple wiper modules or climate controls to autonomous-driving systems. The TSZ182 is in production now in the Mini-SO8 or DFN8 2mm x 2mm package, priced from $0.97 for orders of 1000 units. For further information please visit www.st.com/tsz182-pr

Ricoh launches 4A PWM step-down DCDC converter for industrial, automotive and consumer applications Ricoh Europe (Netherlands) B.V. Semiconductor Support Centre has launched the new 4A synchronous buck DC/DC converter RP510 with an input voltage range up to 5.5V and an optional fixed or adjustable output voltage range from 0.8V to 3.3V. The DC/DC converter supports Power Supplies or Point of Load converters for Microprocessors, FPGAs or DSPs. Point of Load power supplies solve the challenge of high peak current demands and low noise margins, required by high-performance processors, by placing individual power supply regulators close to their point of use. The device features a range of protection circuits contributing to the safe operation of the application. A Power-Good (PG) output provides a fault signal to the system when the device is not ready for regular operation or when any of the protection circuits or states are active. An Under Voltage Lock Out (UVLO) function disables the chip below a minimum input voltage level. The Thermal Shutdown function protects the device during an overload condition and disables it when exceeding a temperature threshold. The Output Over Voltage Detection (OVD) and Under Voltage Detection (UVD) indicate a fault signal when the

Intersil Battery Charger Extends Backup Battery Life of Automotive eCall Systems Intersil Corporation (NASDAQ: ISIL), a leading provider of innovative power management and precision analog solutions today announced the ISL78693, a 3.6V single- cell battery charger that extends the life of Lithium Iron Phosphate (LiFePO4) batteries used in automotive emergency call (eCall) systems. The ISL78693 battery charger offers up to 4x lower leakage current (3uA) than competitive chargers, allowing the eCall backup battery to remain charged for a longer period of time. See a demonstration of the ISL78693 in Intersil’s booth #E30- 11 at the Automotive World conference, January 18-20 in
