The ADP1870 / ADP1871?are versatile current-mode, synchronous step-down controllers that provide superior transient response, optimal stability, and current-limit protection by using a constant on-time, pseudo-fixed frequency with a programmable current limit, current-control scheme. In addition, these devices offer optimum performance at low duty cycles by utilizing valley current-mode control architecture. This allows the ADP1870 / ADP1871 to drive all N-channel power stages to regulate output voltages as low as 0.6 V.The ADP1871 is the power saving mode (PSM) version of the device and is capable of pulse skipping to maintain output regulation while achieving improved system efficiency at light loads (see the Power Saving Mode (PSM) Version (ADP1871) section for more information).Available in three frequency options (300 kHz, 600 kHz, and 1.0 MHz, plus the PSM option), the ADP1870 / ADP1871 are well suited for a wide range of applications that require a single-input power supply range from 2.95 V to 20 V. Low voltage biasing is supplied via a 5 V internal LDO.In addition, an internally fixed soft start period is included to limit input in-rush current from the input supply during startup and to provide reverse current protection during soft start for a precharged output. The low-side current-sense, current-gain scheme and integration of a boost diode, along with the PSM/forced pulse width modulation (PWM) option, reduce the external part count and improve efficiency.The ADP1870 / ADP1871 operate over the -40?C to +125?C junction temperature range and are available in 10-lead MSOP package.

The ADPD4200 operates as a complete multimodal sensor front end, stimulating up to four light emitting diodes (LEDs) and measuring the return signal on up to four separate current inputs. Twelve time slots are available, enabling 12 separate measurements per sampling period.The data output and functional configuration utilize a serial port interface (SPI) on the ADPD4200. The control circuitry includes flexible LED signaling and synchronous detection. The device uses a 1.8 V analog core and 1.8 V or 3.3 V compatible digital input/output (I/O).The analog front end (AFE) rejects signal offsets and corruption from asynchronous modulated interference, typically from ambient light, eliminating the need for optical filters or externally controlled dc cancellation circuitry. Multiple operating modes are provided, enabling the ADPD4200 to be a sensor hub for synchronous measurements of photodiodes, biopotential electrodes, resistance, capacitance, and temperature sensors.The ADPD4200 is available in a 2.619 mm ? 1.804 mm, 0.40 mm pitch, 24-ball WLCSP.Analog Devices is in the process of updating documentation to provide terminology and language that is culturally appropriate. This is a process with a wide scope and will be phased in as quickly as possible.
