ADP5134ACPZ-R7

Overview

The ADP5134ACPZ-R7 is a power management IC featuring two high-efficiency synchronous buck converters and two low-dropout linear regulators. It operates with an input voltage range of 2.5 V to 5.5 V. Each buck converter delivers up to 1.2 A, while each LDO provides 300 mA. The device integrates a 3 MHz switching frequency for compact external components. Quiescent current is specified at 10 uA. It includes power good indicators and supports forced PWM mode. The component is housed in a 24-pin LFCSP package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates dual synchronous buck converters and dual LDOs for comprehensive power distribution
• Supports forced pulse-width modulation operation via the MODE pin for noise-sensitive applications
• Includes power good monitoring signals for system status indication
• Enables miniaturized designs through high-frequency switching capabilities

Applications

• Processor system power management requiring multiple regulated rails
• Portable electronic devices utilizing lithium-ion battery sources
• Industrial control systems demanding wide operating temperature ranges
• Embedded systems needing compact power solutions with low quiescent current

Procurement Notes

Verify the specific suffix R7 indicates tape and reel packaging configuration. Confirm the LFCSP-24 package variant matches your PCB footprint requirements. Ensure compatibility with the 2.5 V to 5.5 V input voltage range for your target application. Check for moisture sensitivity level classifications prior to surface mount assembly processes.

Selection Notes

Select this component when designing systems requiring four distinct output voltages from a single integrated circuit. It is suitable for applications prioritizing board space reduction due to the high switching frequency. Consider the thermal performance of the LFCSP package for heat dissipation needs. Verify that the 1.2 A buck and 300 mA LDO currents meet the load requirements of the connected subsystems.
