Product details
Overview
ADP1610ARMZ-R7 from Analog Devices is a 1.2 MHz DC-to-DC step-up switching converter with integrated 1.2 A/0.2 Ω power switch, adjustable output up to 12 V, ±3% overall regulation accuracy, and pin-selectable 700 kHz or 1.2 MHz PWM frequency - used in TFT LCD bias supplies and portable devices requiring compact, high-efficiency boost conversion.
For engineers reviewing the ADP1610ARMZ-R7 datasheet, ADP1610ARMZ-R7 pinout, ADP1610ARMZ-R7 application, or ADP1610ARMZ-R7 equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, and confirmed alternative options for space-constrained boost converter designs.
Technical Context
The ADP1610ARMZ-R7 implements current-mode PWM control with internal transconductance error amplifier (100 μA/V), ramp-compensated comparator, and pulse-by-pulse peak current limiting at 2.0 A. Its feedback loop references a precise 1.230 V bandgap voltage (±1.5% over temperature) and supports external RC compensation on the COMP pin for stability across input/output ranges.
Switching frequency is set by RT pin connection: GND yields 700 kHz (optimized for efficiency), IN yields 1.2 MHz (enabling smaller inductors like 4.7 µH). Soft start is controlled by an internal 3 µA current source charging an external capacitor on SS, preventing inrush during startup or wake-up from shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 5.5 V - supports single-cell Li-ion, 3.3 V logic rails, and dual-cell alkaline inputs without pre-regulation. |
| Output Voltage Range | Adjustable from VIN to 12 V - enables flexible bias generation for TFT gate drivers (e.g., +10 V/-7 V) using external resistor divider. |
| Peak Switch Current Limit | 2.0 A - sets maximum deliverable load current under low-VIN/high-VOUT conditions; derates with temperature (see Fig. 8). |
| Feedback Reference Voltage | 1.230 V ±1.5% - defines output setpoint accuracy; used with R1/R2 divider where R2 ≤ 10 kΩ to minimize bias-current error. |
| Quiescent Current (Active) | 1–2 mA at 1.23 MHz - determines light-load efficiency and battery runtime in always-on portable systems. |
| Shutdown Current | 0.01–10 µA - enables ultra-low-power system sleep modes; SD pin threshold is VIH ≥ 2.2 V, VIL ≤ 0.6 V. |
| Efficiency | Up to 92% at 10 V/200 mA - achieved with integrated 0.2 Ω switch and optimized for ceramic capacitors and small inductors (e.g., 4.7 µH @ 1.2 MHz). |
Pinout & Package
ADP1610ARMZ-R7 is housed in a RoHS-compliant 8-lead MSOP package (3.0 mm × 3.0 mm × 1.1 mm height), optimized for thin portable and display applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - COMP | Compensation node | Connects external RC network to stabilize feedback loop; impedance directly affects transient response and phase margin. |
| 2 - FB | Feedback input | Senses output via resistive divider; 10 nA bias current requires R2 ≤ 10 kΩ to limit setpoint error. |
| 3 - SD | Shutdown control | Logic-level enable: <0.6 V = shutdown (10 nA IQ), >2.2 V = active; no internal pull-up/down. |
| 4 - GND | Power and signal ground | Common return for IN, SW, FB, COMP, SS, RT, SD; must be low-impedance plane for noise immunity. |
| 5 - SW | Switching node | Drives external inductor; carries pulsed 1.2 A peak current; requires tight layout to minimize EMI and voltage spikes. |
| 6 - IN | Main power input | Supplies internal circuitry and switch; requires ≥10 µF low-ESR ceramic bypass capacitor placed adjacent to pin. |
| 7 - RT | Frequency select | GND = 700 kHz, IN = 1.2 MHz - selects trade-off between efficiency (lower fSW) and component size (higher fSW). |
| 8 - SS | Soft start timing | Charged by internal 3 µA source; 20 nF typical for <0.3 ms soft start and negligible inrush at 3.3 V → 10 V. |
Key Features
| Feature | Design Value |
|---|---|
| Fully integrated 1.2 A, 0.2 Ω power switch | Eliminates external MOSFET and gate driver; reduces BOM count and PCB area in space-critical designs. |
| Pin-selectable 700 kHz / 1.2 MHz PWM frequency | Enables optimization: 700 kHz for max efficiency with 10 µH inductor, 1.2 MHz for miniaturization with 4.7 µH inductor. |
| Adjustable soft start via external capacitor | Prevents input inrush and output overshoot; 20 nF yields ~0.3 ms ramp time for 3.3 V → 10 V conversion. |
| Input undervoltage lockout (UVLO) | Activates at VIN rising = 2.4 V ±0.1 V with 220 mV hysteresis - prevents erratic operation during brownout or battery depletion. |
| 92% peak efficiency | Validated at 10 V/200 mA with 1.2 MHz switching, 4.7 µH inductor, and ceramic input/output caps - extends battery life in portable gear. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61088RHLR | Higher 5-A switch, wider 2.7–12 V input, fixed 500 kHz/2 MHz selection - no pin-selectable frequency; requires external compensation. | Better suited for >1 A loads and higher input voltages; less optimal for sub-500 mA, ultra-thin designs due to larger QFN package. | Choose TPS61088RHLR when output current exceeds 400 mA or input may exceed 5.5 V; ADP1610ARMZ-R7 remains preferred for <12 mm² footprint and precise 1.230 V reference. |
| MAX17222ETA+ | Lower 0.5-A switch, 1.2 MHz fixed frequency, 0.65 V min input, no UVLO hysteresis - smaller 6-bump WLP package. | Targeted at ultra-low-power coin-cell applications (<100 mA); lacks adjustable soft start and RT-based frequency flexibility. | Choose MAX17222ETA+ only for sub-100 mA, sub-1 mm height constraints; ADP1610ARMZ-R7 provides superior current capability, thermal robustness, and design flexibility. |
Compared with TPS61088RHLR and MAX17222ETA+, the ADP1610ARMZ-R7 uniquely balances 1.2 A capability, 1.230 V precision reference, pin-selectable frequency, and MSOP footprint - making it optimal for mid-power portable and display bias applications demanding accuracy, size, and thermal reliability.

FAQ
What is the maximum output voltage achievable with the ADP1610ARMZ-R7?
The ADP1610ARMZ-R7 supports an adjustable output voltage up to 12 V, set by an external resistive divider connected to the FB pin. The device maintains ±3% overall regulation accuracy across line, load, and temperature when configured within its 2.5 V to 5.5 V input range. Output voltages above 12 V are not supported and may damage the internal switch or compromise stability.
How does the RT pin affect switching frequency and design trade-offs for the ADP1610ARMZ-R7?
The RT pin on the ADP1610ARMZ-R7 selects between two fixed frequencies: connecting RT to GND sets 700 kHz (optimized for peak efficiency), while connecting RT to IN sets 1.2 MHz (enabling smaller external inductors and capacitors). At 1.2 MHz, a 4.7 µH inductor suffices for most 10 V outputs; at 700 kHz, a 10 µH inductor improves efficiency but increases solution size. Frequency choice directly impacts EMI filtering requirements and thermal performance.
Can the ADP1610ARMZ-R7 operate reliably across the full industrial temperature range?
Yes, the ADP1610ARMZ-R7 is specified and tested for continuous operation from −40°C to +85°C ambient temperature. Key parameters-including feedback reference voltage (1.230 V ±0.015 V), switch on-resistance (200–350 mΩ), and oscillator frequency-are characterized across this range. The MSOP package's thermal resistance (θJA = 142°C/W on 4-layer board) ensures safe junction temperatures even at full 1.2 A load under worst-case conditions.
What is the role of the SS pin and how is soft start time determined for the ADP1610ARMZ-R7?
The SS pin on the ADP1610ARMZ-R7 controls soft start by sourcing a precise 3 µA current into an external capacitor (CSS) connected to GND. Soft start time tSS ≈ (CSS × 1.23 V) / 3 µA - e.g., 20 nF yields ~8.2 ms ramp time. This linearly limits COMP voltage rise, capping peak switch current at startup and preventing input inrush. CSS can be omitted for fastest start-up, though peak current may increase significantly.
Does the ADP1610ARMZ-R7 include input undervoltage lockout, and how does it behave?
Yes, the ADP1610ARMZ-R7 features built-in undervoltage lockout (UVLO) that disables switching when VIN falls below 2.4 V (typical) during power-up or brownout. It includes 220 mV hysteresis, so the device re-enables only when VIN rises above ~2.62 V. This prevents erratic operation, excessive switch stress, and unregulated output during low-input conditions - critical for battery-powered systems near end-of-discharge.
