TPS5430 Pinout

Description
The TPS5430/TPS5431 is a high-output-current PWM converter that integrates a low resistance high side N-channel MOSFET. Included on the substrate with the listed features are a high performance voltage error amplifier that provides tight voltage regulation accuracy under transient conditions; an undervoltage-lockout circuit to prevent start-up until the input voltage reaches 5.5 V; an internally set slow-start circuit to limit inrush currents; and a voltage feed-forward circuit to improve the transient response. Using the ENA pin, shutdown supply current is reduced to 18 μA typically. Other features include an active-high enable, overcurrent limiting, overvoltage protection and thermal shutdown. To reduce design complexity and external component count, the TPS5430/TPS5431 feedback loop is internally compensated. The TPS5431 is intended to operate from power rails up to 23 V. The TPS5430 regulates a wide variety of power sources including 24-V bus.

Description

The AD7684 is a 16-bit, charge redistribution, successive approximation, PulSAR® analog-to-digital converter (ADC) that operates from a single power supply, VDD, between 2.7 V to 5.5 V. It contains a low power, high speed, 16-bit sampling ADC with no missing codes, an internal conversion clock, and a serial, SPI-compatible interface port. The part also contains a low noise, wide bandwidth, short aperture delay, track-and-hold circuit. On the CSfalling edge, it samples the voltage difference between +IN and –IN pins. The reference voltage, REF, is applied externally and can be set up to the supply voltage. Its power scales linearly with throughput. The AD7684 is housed in an 8-lead MSOP, with an operating emperature specified from −40°C to +85°C.

Features

1. 16-bit resolution with no missing codes
2. Throughput: 100 kSPS
3. INL: ±1 LSB typical, ±3 LSB maximum
4. True differential analog input range: ±VREF 0 V to VREFwith VREFup to VDD on both inputs
5. Single-supply operation: 2.7 V to 5.5 V
6. Serial interface SPI-/QSPI-/MICROWIRE-/DSP-compatible
7. Power dissipation : 4 mW @ 5 V , 1.5 mW @ 2.7 V , 150 μW @ 2.7 V/10 kSPS
8. Standby current: 1 nA

Applications

1. Battery-powered equipment
2. Data acquisition
3. Instrumentation
4. Medical instruments
5. Process control
