The ISL8023IRTAZ is a high-efficiency, monolithic, synchronous step-down DC/DC converter from Renesas Electronics Corporation. It is capable of delivering up to 3A of continuous output current from an input voltage range of 2.7V to 5.5V. This makes it suitable for applications powered by a single Li-ion cell, three NiMH cells, or a regulated 5V input. citeturn0search3

Key Features:

• High Efficiency: The device integrates a low on-resistance P-Channel (45mΩ) high-side FET and N-Channel (19mΩ) low-side FET to maximize efficiency and minimize external component count.

• Adjustable Switching Frequency: The pulse-width modulator (PWM) operation frequency is adjustable from 500kHz to 4MHz, allowing for the use of small external components.

• Low Dropout Operation: Supports 100% duty-cycle operation, enabling a dropout voltage of less than 200mV at 3A output current.

• Light Load Operation Modes: Can be configured for either discontinuous or forced continuous operation at light loads. Forced continuous mode reduces noise and RF interference, while discontinuous mode enhances efficiency by reducing switching losses.

• Protection Features: Includes internal hiccup mode current limiting during short circuit and overcurrent conditions, as well as overvoltage and over-temperature protection.

• Power-Good Indicator: Provides a power-good output voltage monitor to indicate when the output is in regulation.

• Compact Package: Offered in a space-saving 16-lead 3x3mm TQFN package with an exposed pad for improved thermal performance.

These features make the ISL8023IRTAZ ideal for applications requiring efficient power conversion in a compact form factor, such as portable devices, point-of-load regulation, and distributed power systems. citeturn0search3

Here’s what I found about ISL32495EIBZ (Renesas/Intersil):

The ISL32495EIBZ is a fault‑protected, half‑duplex RS‑485/RS‑422 transceiver designed for high-reliability communication at 5 V, featuring robust protection and IEC-grade performance.

• Bus Protection: Transceiver pins are fault‑protected up to ±60 V, with overvoltage tolerance up to ±80 V 

• Extended Common‑Mode Range (CMR) up to ±25 V, exceeding RS‑485 requirements by more than 2× 

• ESD Immunity: ±16.5 kV (HBM) on data lines without latch‑up

• Supply Voltage: 5 V (4.5–5.5 V range) 

• Data Rate: Up to 1 Mbps in half‑duplex mode 

• Supply Current: Approx. 2.3 mA, with ultra‑low shutdown current (~10 µA) 

• Receiver Unit Load: ¼ unit load allows up to 128 devices on a single bus 

• Fail‑Safe Receiver: Output defaults to high if inputs float, short, or idle 

• Hot‑Plug Support: Tx/Rx remain tri-stated during power transitions 

• Package: 8‑lead SOIC‑8 (SOICN), ~4.9 × 3.9 mm 

• Operating Temp Range: −40 °C to +85 °C 

• RoHS-compliant, lead‑free Pb‑Free finish 

• High‑reliability industrial field buses, including PROFIBUS and smart‑grid deployments

• Metering networks and distributed sensor communication systems

• Systems needing high node counts and protection against wiring faults or ESD

• Environmentally harsh settings with common-mode voltage swings or transient bus voltages

The suffix EIBZ denotes the specific packaging style (SOIC, RoHS). Available options include tube packaging (ISL32495EIBZ) and tape & reel (ISL32495EIBZ‑T), useful for automated SMT assembly 

• Excellent fit for harsh wiring systems with high risk of overvoltage or ESD events.

• Use fail-safe ensures defined logic-level behavior even if bus is idle or faulted.

• Shutdown mode supports low-power standby states.

• Ensure proper terminations and layout practices to maintain signal integrity.
