The MAX16977 is a 2A, current-mode, step-down converter with an integrated high-side switch. The device is designed to operate with input voltages from 3.5V to 36V while using only 30µA quiescent current at no load. The switching frequency is adjustable from 1MHz to 2.2MHz by an external resistor and can be synchronized to an external clock. The output voltage is pin selectable to be 5V fixed or adjustable from 1V to 10V. The wide input voltage range along with its ability to operate at high duty cycle during undervoltage transients make the device ideal for automotive and industrial applications.

The 71M6543F/71M6543H are Teridian's 4th-generation polyphase metering system-on-chips (SoCs) with a 5MHz, 8051-compatible MPU core, low-power real-time clock (RTC) with digital temperature compensation, flash memory, and LCD driver. Our Single Converter Technology® with a 22-bit delta-sigma analog-to-digital converter (ADC), three or four analog inputs, digital temperature compensation, precision voltage reference, and a 32-bit computation engine (CE) supports a wide range of metering applications with very few external components.

The 71M6543F/71M6543H support optional interfaces to the 71M6x01 series of isolated sensors, which offer BOM cost reduction, immunity to magnetic tamper, and enhanced reliability. Other features include an SPI™ interface, advanced power management, ultra-low-power operation in active and battery modes, 3/5KB shared RAM, and 32/64KB of flash memory that can be programmed in the field with code and/or data during meter operation and the ability to drive up to six LCD segments per SEG driver pin. High processing and sampling rates combined with differential inputs offer a powerful metering platform for residential meters.

Green LED Replaces LDO Regulator
Abstract: In systems in which a microcontroller must communicate with peripheral devices that operate at different supply voltages, a level translator may be necessary. This design idea explains how for low-power loads, a single green LED can replace a 1.8V LDO regulator in a level-translator circuit.
