Product details
Overview
ADP1053ACPZ-RL from Analog Devices is a 3-channel digital power supply controller implementing voltage-mode PWM control with 625 ps resolution, remote differential voltage sensing on two regulated channels, and PMBus-compliant programmability. It delivers independent OVP/OCP/OTP protection per channel and supports interleaved configurations for high-efficiency isolated and nonisolated DC-DC converters in telecom and server power systems.
For engineers reviewing the ADP1053ACPZ-RL datasheet, ADP1053ACPZ-RL pinout, ADP1053ACPZ-RL application, or ADP1053ACPZ-RL equivalent, key selection criteria include its 40-lead LFCSP package, 50 kHz–625 kHz programmable switching frequency, dual-channel differential current sense (CS2±_A/B), and EEPROM-based configuration persistence across power cycles.
Technical Context
The ADP1053ACPZ-RL integrates an 8-PWM engine configurable as two regulated feedback-controlled channels plus one unregulated fixed-duty channel, with independent frequency programming and synchronization capability. Its Σ-Δ ADCs provide 12-bit voltage sensing (VS±_A/B) and 11-/12-bit current sensing (CS1_A/B, CS2±_A/B), enabling precise loop control and fast OCP response down to 58 ns latency.
Digital compensation supports three poles and two zeros per channel, while programmable feedforward enhances line regulation. The device uses a 200 MHz PLL core, operates from a single 3.3 V supply, and stores calibrated settings-including trim values for CS2 offset/gain and RTD linearization-in on-board EEPROM with CRC integrity checking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital power controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC2897A | Analog controller with external compensation; no integrated ADC, EEPROM, or PMBus interface | Lacks digital telemetry, fault logging, and programmable sequencing-requires external MCU for similar functionality | Choose UCC2897A only for cost-sensitive analog designs where digital features are unnecessary |
| ISL68127 | Single-channel digital multiphase controller with integrated MOSFET drivers; supports up to 7 phases | Optimized for CPU/GPU VRMs-not suitable for dual-isolated-channel architectures like ADP1053ACPZ-RL | Select ISL68127 when designing high-current single-rail VRMs, not multi-output isolated supplies |
Compared with UCC2897A and ISL68127, the ADP1053ACPZ-RL uniquely supports dual isolated regulated outputs with differential sensing, on-chip EEPROM storage, and full PMBus programmability-making it the only option among the three for intelligent, field-upgradable, multi-rail industrial power systems.

FAQ
What is the operating supply voltage range for the ADP1053ACPZ-RL?
The ADP1053ACPZ-RL operates from a single 3.0 V to 3.6 V supply (VDD), with typical current draw of 30 mA during normal operation. Its UVLO threshold is 3.0 V (rising) and 2.85 V (falling), ensuring reliable startup and shutdown behavior. The internal VCORE regulator provides a stable 2.5 V ±0.2 V supply for the digital core, decoupled by a 330 nF capacitor between VCORE and DGND as specified in the datasheet.
Does the ADP1053ACPZ-RL support differential current sensing on both regulated channels?
Yes, the ADP1053ACPZ-RL supports true differential current sensing on both Channel A and Channel B via dedicated CS2+_A/CS2−_A and CS2+_B/CS2−_B pins, with ±120 mV full-scale range and 12-bit resolution. This enables accurate high-side or low-side current measurement with user-trimmable offset and gain, critical for precise OCP and current balance in interleaved configurations.
How does the ADP1053ACPZ-RL handle power-good signaling for dual outputs?
The ADP1053ACPZ-RL provides independent open-drain PGOOD_A and PGOOD_B pins, each driven low when their respective POWER_SUPPLY_A/B, UVP_A/B, SOFTSTART_FILTER_A/B, or EEPROM_CRC flags are asserted. These signals can be externally pulled up to any compatible logic voltage and are fully programmable-enabling custom power sequencing and system-level fault reporting without additional circuitry.
Can the ADP1053ACPZ-RL store configuration settings permanently?
Yes, the ADP1053ACPZ-RL includes 8 kB of on-board EEPROM that retains all programmed parameters-including compensation coefficients, protection thresholds, sequencing delays, and calibration trims-even after power loss. Settings are saved using the STORE_USER_ALL command and restored at boot via RESTORE_USER_ALL, with built-in CRC checksum validation to ensure integrity.
What thermal management provisions does the ADP1053ACPZ-RL include?
The ADP1053ACPZ-RL integrates two independent OTP circuits with programmable thresholds, interfacing with 100 kΩ NTC thermistors via RTD1/RTD2 pins. It supports factory-trimmed linearization for ±5°C accuracy from 25°C to 125°C and provides real-time temperature readings via PMBus. The 40-lead LFCSP package has θJA = 28.36°C/W and requires the exposed thermal pad to be soldered to AGND for optimal heat dissipation.
