Product details
Overview
ADP2116ACPZ-R7 from Analog Devices is a configurable dual-channel synchronous step-down DC-DC regulator supporting 3 A/3 A or 3 A/2 A independent outputs, or 6 A combined interleaved output. It operates from 2.75 V to 5.5 V input, delivers ±1.5% reference accuracy, and supports selectable switching frequencies up to 2 MHz - ideal for point-of-load regulation in telecom and industrial power systems.
For engineers reviewing the ADP2116ACPZ-R7 datasheet, ADP2116ACPZ-R7 pinout, ADP2116ACPZ-R7 application, or ADP2116ACPZ-R7 equivalent, key selection criteria include dual-phase 180° phase shift for reduced input ripple, independent enable/power-good signals per channel, programmable soft start, and thermal/overcurrent protection with hiccup mode recovery.
Technical Context
The ADP2116ACPZ-R7 implements current-mode control with dual PWM channels operating in either independent or interleaved (180° phase-shifted) configurations. Its integrated P-channel high-side and N-channel low-side MOSFETs support peak current limits of 3.5–5.3 A per channel, configurable via OPCFG pin resistor selection.
It features a bidirectional SYNC/CLKOUT pin that functions as either external synchronization input (200 kHz–2 MHz) or internal 90° out-of-phase clock output, enabling stackable multiphase designs. The device uses an optimized gate slew rate to minimize EMI while maintaining fast transient response through error amplifier transconductance of 550 µA/V.
Key Specifications

| Package | 32-lead, 5 mm × 5 mm LFCSP with exposed thermal pad - enables high-power dissipation in compact footprint. |
Pinout & Package
ADP2116ACPZ-R7 is housed in a 32-lead, 5 mm × 5 mm LFCSP package with exposed thermal pad connected to signal/analog ground. Pin functions are validated per Analog Devices Rev. B datasheet Figure 3 and Table 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Analog/Digital Ground Reference | Must connect to signal/analog ground plane before power ground - critical for noise-sensitive feedback stability. |
| COMP1 / COMP2 (Pins 2, 7) | Error Amplifier Output | Connect RC compensation network to GND; tied together for multiphase operation to synchronize control loops. |
| FREQ (Pin 3) | Frequency Select Input | Resistor-to-GND sets switching frequency (300/600/1200 kHz); determines minimum on/off times and LC filter sizing. |

| VIN1–VIN6 (Pins 25–27, 14–16) | High-Side MOSFET Power Inputs | Three dedicated VIN pins per channel reduce IR drop and improve current sharing in high-current paths. |
| PGND1–PGND4 (Pins 22–20, 21) | Power Ground Returns | Separate PGND pins per switch leg minimize ground bounce and improve EMI performance in dual-phase layout. |
| SW1–SW4 (Pins 24, 23, 18, 17) | Switch Node Outputs | SW1/SW2 for Channel 1; SW3/SW4 for Channel 2 - tie pairs together before LC filter to reduce loop area and parasitic inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-phase interleaving | 180° phase shift between channels cuts input ripple current by ~50%, reducing required input capacitance and EMI filtering. |
| Configurable current limit | Selectable 3.5–5.3 A or 2.4–4.0 A per channel via OPCFG resistor - matches load requirements without overdesigning MOSFET stress. |

FAQ
What input voltage range does the ADP2116ACPZ-R7 support?
The ADP2116ACPZ-R7 supports an input voltage range of 2.75 V to 5.5 V. This makes it compatible with standard intermediate bus voltages such as 3.3 V and 5 V, and ensures reliable operation across wide variations including cold-crank conditions in automotive auxiliary systems. The device includes undervoltage lockout (UVLO) with 2.75 V rising threshold and 2.47 V falling threshold to prevent erratic startup.
How is output voltage configured on the ADP2116ACPZ-R7?
The ADP2116ACPZ-R7 supports both fixed and adjustable output voltages per channel. Fixed outputs (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, or 3.3 V) are selected by connecting V1SET or V2SET to GND via specific resistor values per Table 4 in the datasheet. Adjustable mode uses a resistor divider from VOUT to GND with FBx pins, enabling outputs down to 0.6 V with ±1.5% reference accuracy over temperature.
Does the ADP2116ACPZ-R7 support synchronization with external clocks?
Yes, the ADP2116ACPZ-R7 supports external synchronization via its bidirectional SYNC/CLKOUT pin. When SCFG is tied to GND, the pin accepts an external clock from 200 kHz to 2 MHz. The internal oscillator frequency must be set close to the external clock using the FREQ pin resistor to ensure stable locking. This feature enables noise reduction in systems with multiple switching regulators.
What thermal protection mechanisms does the ADP2116ACPZ-R7 include?
The ADP2116ACPZ-R7 incorporates thermal shutdown at 150°C junction temperature with 25°C hysteresis, ensuring automatic recovery after cooling. It also features hiccup-mode overcurrent protection triggered after eight consecutive current-limit cycles, limiting power dissipation during sustained overload. These protections operate independently per channel and require no external components.
Can the ADP2116ACPZ-R7 operate in forced PWM mode?
Yes, the ADP2116ACPZ-R7 can operate in forced PWM mode, which maintains constant switching frequency even at light loads. This mode is selected via the OPCFG pin configuration and is ideal for noise-sensitive applications such as RF or high-resolution ADC circuits where pulse-skipping artifacts could interfere with signal integrity. Efficiency remains competitive down to ~10% load in this mode.
