Product details

Overview

ADP1882ARMZ-0.6-R7 from Analog Devices is a synchronous current-mode PWM buck controller with constant on-time architecture, designed for high-efficiency DC/DC conversion in space-constrained power supplies. It operates from 2.75 V to 20 V input, delivers output as low as 0.8 V with ±1.0% reference accuracy, supports all-N-channel MOSFET stages, and runs at a fixed 600 kHz switching frequency in a 10-lead MSOP package.

For engineers reviewing the ADP1882ARMZ-0.6-R7 datasheet, ADP1882ARMZ-0.6-R7 pinout, ADP1882ARMZ-0.6-R7 application, or ADP1882ARMZ-0.6-R7 equivalent, this controller is selected for telecom/server core voltage regulation where fast transient response, valley current-mode stability, and integrated bootstrap diode reduce external component count and improve light-load efficiency without PSM.

Technical Context

The ADP1882ARMZ-0.6-R7 implements a valley current-mode control scheme with pseudo-fixed-frequency operation, enabling stable regulation at low duty cycles down to ~4% (e.g., 0.8 V out from 20 V in). Its constant on-time architecture provides superior line and load transient response without requiring loop compensation components.

It integrates a bootstrap diode between VDD and BST, eliminates the need for an external current-sense resistor via DRVL-based gain programming, and features precision enable threshold (235–330 mV), thermal shutdown at 155°C, and hiccup-mode short-circuit protection. The device does not support power saving mode (PSM) - that function is exclusive to the ADP1883 variant.

Key Specifications

Parameter	Value and Actual Design Meaning
Switching Frequency	Fixed 600 kHz - enables compact magnetics and predictable EMI profile; minimum off time ≥340 ns ensures stable operation at high VIN/VOUT ratios.
Output Voltage Range	0.8 V minimum with ±1.0% reference accuracy at 25°C - supports modern DSP/FPGA core rails requiring tight regulation tolerance.
Input Voltage Range	VIN: 2.75 V to 20 V; VDD bias: 2.75 V to 5.5 V - allows direct use of 3.3 V or 5 V system rails for controller bias while accepting wide-range primary inputs.
Current-Sense Architecture	Low-side sensing via DRVL pin with resistor-programmable gain (e.g., 6.6 V/V with 22 kΩ) - eliminates sense resistor losses and simplifies layout versus high-side sensing.
Driver Performance	DRVH rise/fall times ≤25 ns/11 ns; DRVL rise/fall ≤18 ns/16 ns - supports fast-switching N-MOSFETs with minimal dead-time loss and reduced gate drive loss.
Thermal & Protection	Thermal shutdown at 155°C with 15°C hysteresis; hiccup-mode current limit with 6 ms timing - prevents thermal runaway and enables safe recovery after overload.
Quiescent Current	1.1 mA operating IQ; 140 μA shutdown current - balances light-load efficiency and rapid wake-up capability without PSM overhead.

Pinout & Package

ADP1882ARMZ-0.6-R7 is housed in a thermally enhanced 10-lead MSOP package (3 mm × 3 mm, 0.5 mm pitch) with exposed pad for improved heat dissipation. Pin 1 is VIN; pin 4 is GND (analog ground); pin 7 is PGND (power ground); pin 10 is BST. Thermal resistance θJA is 171.7°C/W on a 4-layer board.

Pin/Terminal	Circuit Role	Design Meaning
VIN (Pin 1)	High-side power input	Connects to drain of upper N-MOSFET; accepts up to 20 V - defines maximum input rail voltage for the buck stage.
COMP/EN (Pin 2)	Error amplifier output / enable input	Open-drain COMP output for loop compensation; logic-low (<285 mV) disables IC - enables precise sequencing and fault shutdown.
FB (Pin 3)	Feedback node	Connects to resistor divider from VOUT; regulates output to 0.8 V reference - sets output voltage via R_top/R_bot ratio.
GND (Pin 4)	Analog ground reference	Reference for error amp, FB, COMP - must be isolated from noisy PGND to prevent regulation noise coupling.
VDD (Pin 5)	Bias supply input	Supplies internal circuitry and gate drivers; requires 1 μF bypass to PGND - powers controller independently of VIN.
DRVL (Pin 6)	Lower MOSFET gate driver + current-sense gain	Drives source of low-side N-MOSFET; also sets current-sense gain via resistor to PGND - eliminates external sense resistor.
PGND (Pin 7)	Power ground return	Return path for low-side MOSFET source and DRVH/DRVL drivers - must connect directly to power plane under inductor and MOSFETs.
DRVH (Pin 8)	Upper MOSFET gate driver	Drives gate of high-side N-MOSFET; bootstrapped from BST - requires external BST capacitor (typically 0.1 μF) from BST to SW.
SW (Pin 9)	Switch node	Connection point between high- and low-side MOSFETs; ties to inductor and BST capacitor - critical for EMI and layout integrity.
BST (Pin 10)	Bootstrap supply for high-side driver	Internal diode connects VDD to BST; external capacitor from BST to SW generates floating gate drive voltage - enables N-MOS high-side switch.

Key Features

Feature	Design Value
Valley current-mode control	Enables stable operation at ultra-low duty cycles (e.g., 0.8 V from 20 V) without slope compensation or complex loop tuning.
Integrated bootstrap diode	Eliminates external Schottky diode requirement, reducing BOM count and PCB area while maintaining robust high-side drive.
Resistor-programmable current-sense gain	Supports multiple gain options (e.g., 6.6 V/V with 22 kΩ) to match MOSFET R_DS(on) and optimize current-limit accuracy.
Precision enable threshold	235–330 mV logic-high threshold with 35 mV hysteresis - enables clean, noise-immune power sequencing in multi-rail systems.
Start-up into precharged output	Prevents reverse current flow during soft-start when output capacitor is already charged - protects upstream sources and downstream loads.

Equivalent & Alternatives

The following parts are listed as comparable options for similar synchronous buck controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADP1883ARMZ-0.6-R7	Identical pinout and electrical specs, but adds Power Saving Mode (PSM) for pulse-skipping at light loads.	Preferred for battery-powered or always-on systems requiring <100 μA quiescent current below 100 mA load.	Select ADP1883ARMZ-0.6-R7 only if PSM is required; ADP1882ARMZ-0.6-R7 offers lower complexity and avoids PSM-related output ripple.
TPS54620RGYR	600 kHz, 17 V max VIN, 0.8 V reference, but uses external current-sense resistor and no integrated bootstrap diode.	Suitable where design flexibility (e.g., custom current limit, discrete bootstrap) outweighs BOM reduction goals.	Choose TPS54620RGYR when needing adjustable current limit threshold or higher VIN margin beyond 20 V.

Compared with ADP1883ARMZ-0.6-R7, the ADP1882ARMZ-0.6-R7 omits PSM to simplify control behavior and eliminate low-load ripple; compared with TPS54620RGYR, it reduces component count via integrated bootstrap and resistorless current sensing - favoring compact, cost-sensitive telecom/server designs.

FAQ

What is the key functional difference between ADP1882ARMZ-0.6-R7 and ADP1883ARMZ-0.6-R7?

The ADP1882ARMZ-0.6-R7 lacks Power Saving Mode (PSM), while the ADP1883ARMZ-0.6-R7 includes PSM for pulse-skipping at light loads. This makes ADP1882ARMZ-0.6-R7 more suitable for applications where consistent 600 kHz switching is preferred - such as EMI-sensitive environments - whereas ADP1883ARMZ-0.6-R7 improves light-load efficiency at the cost of increased output ripple during PSM operation.

Does ADP1882ARMZ-0.6-R7 require an external current-sense resistor?

No, ADP1882ARMZ-0.6-R7 does not require an external current-sense resistor. It uses low-side current sensing via the DRVL pin, with gain set by a resistor from DRVL to PGND (e.g., 22 kΩ yields 6.6 V/V gain). This eliminates sense resistor power loss and layout sensitivity, simplifying design and improving efficiency.

What is the minimum output voltage supported by ADP1882ARMZ-0.6-R7?

The ADP1882ARMZ-0.6-R7 supports a minimum output voltage of 0.8 V, set by its internal reference voltage with ±1.0% accuracy at 25°C and ±0.8% typical drift over −40°C to +125°C. This enables direct regulation of modern low-voltage processor and memory cores without external amplification.

Can ADP1882ARMZ-0.6-R7 start up into a precharged output capacitor?

Yes, ADP1882ARMZ-0.6-R7 supports startup into a precharged output. Its internal soft-start circuitry prevents reverse current flow during initial turn-on, protecting both the input source and downstream loads - a critical feature for hot-swap and redundant power architectures.

What package type and thermal performance does ADP1882ARMZ-0.6-R7 use?

ADP1882ARMZ-0.6-R7 uses a 10-lead MSOP package with exposed pad. On a 4-layer PCB, its thermal resistance is θJA = 171.7°C/W. The exposed pad must be soldered to a thermal pad connected to internal ground planes to achieve rated junction temperature limits (−40°C to +125°C).
