Product details
Overview
ADP1614ACPZ-1.3-R7 from Analog Devices is a 1.3 MHz, 4 A step-up DC-to-DC switching converter with integrated 100 mΩ power switch, adjustable current limit (up to 4 A), 2.5 V–5.5 V input range, and up to 20 V output voltage. It operates in current-mode PWM for fast transient response and supports TFT LCD bias supplies requiring compact, high-efficiency boost conversion.
For engineers reviewing the ADP1614ACPZ-1.3-R7 datasheet, ADP1614ACPZ-1.3-R7 pinout, ADP1614ACPZ-1.3-R7 application, or ADP1614ACPZ-1.3-R7 equivalent, this page delivers verified specifications, validated pin functions, confirmed thermal and efficiency behavior at 1.3 MHz, and real-world alternative selection guidance for space-constrained portable and industrial boost designs.
Technical Context
The ADP1614ACPZ-1.3-R7 implements fixed-frequency current-mode PWM control with internal slope compensation for stability at high duty cycles. Its oscillator is factory-trimmed to 1.3 MHz ±10%, enabling use of sub-10 µH inductors and low-ESR ceramic capacitors without compromising loop stability.
It features a dedicated CLRES pin (Pin 9) for resistor-programmable peak current limit (0.95–4 A), logic-controlled EN pin with 0.3 V/1.6 V thresholds, and soft-start via external capacitor on SS pin with 5.5 µA charging current - all operating within −40°C to +125°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 1.3 MHz (fixed, factory-set; enables <10 µH inductors and compact layout) |
| Input Voltage Range | 2.5 V to 5.5 V (supports single-cell Li-ion, 3.3 V/5 V rails) |
| Max Output Voltage | 20 V (programmable via FB resistive divider; suitable for TFT gate drivers) |
| Peak Current Limit | Up to 4 A (adjustable via external RCL on CLRES pin; supports high-current boost stages) |
| Switch RDS(on) | 50–100 mΩ (typ/max at ISW = 1 A; reduces conduction loss at high load) |
| Efficiency | Up to 94% (measured at VIN = 3.6 V, VOUT = 15 V, ILOAD = 1 A, fSW = 1.3 MHz) |
| Quiescent Current | 7 mA (switching state, no load; balances light-load efficiency and startup speed) |
| Thermal Shutdown | 150°C threshold with 20°C hysteresis (protects against sustained overload in sealed enclosures) |
Pinout & Package
ADP1614ACPZ-1.3-R7 uses a 3 mm × 3 mm, 10-lead LFCSP package with exposed pad (EP) for thermal dissipation. The package height is 0.8 mm, optimized for ultra-thin portable applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (COMP) | Compensation node | Connect RC network to GND to stabilize feedback loop across input/output/load variations |
| 2 (FB) | Feedback input | Senses output voltage via resistive divider; reference is 1.245 V ±1.6% |
| 3 (EN) | Enable control | Logic-high (>1.6 V) enables regulator; logic-low (<0.3 V) shuts down with 0.25 µA quiescent current |
| 4,5 (GND) | Power ground | Dual GND pins reduce ground impedance and improve noise immunity in high-dI/dt paths |
| 6,7 (SW) | Power switch output | Drives external inductor; dual pins share current and reduce trace inductance |
| 8 (VIN) | Main supply input | Accepts 2.5–5.5 V; requires local ≥10 µF bypass capacitor for EMI suppression |
| 9 (CLRES) | Current-limit resistor | Connect external resistor to GND to set peak switch current from 0.95 A to 4 A |
| 10 (SS) | Soft-start capacitor | Capacitor here controls output ramp rate; 68 nF yields ~10 ms startup time |
| 11 (EP) | Exposed thermal pad | Must be soldered to PCB ground plane; improves θJA by >20% vs. no thermal connection |
Key Features
| Feature | Design Value |
|---|---|
| Fixed 1.3 MHz operation | Enables use of 4.7 µH–10 µH inductors and 10 µF–47 µF ceramic output caps - cuts board area by >30% vs. 650 kHz version |
| Adjustable 4 A current limit | Resistor-programmable via CLRES pin; allows precise matching to inductor saturation rating and system fault current requirements |
| Current-mode PWM architecture | Delivers <50 µs load transient recovery (50–150 mA step) and eliminates need for external slope compensation in most CCM designs |
| Integrated protection suite | Includes undervoltage lockout (2.33 V turn-on), thermal shutdown (150°C), and automatic soft-start capacitor discharge during fault recovery |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up DC-to-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61088RHLR | Fixed 1 MHz switching; 5.5 A max current limit; 2.7–5.5 V input; no CLRES pin - current limit set internally | Higher current capability but less flexible current programming; lacks 1.3 MHz option for smallest inductors | Choose when >4 A peak load is required and board space allows slightly larger inductor |
| MAX17222ATA+ | 1.2 MHz switching; 2 A max current limit; 0.4–5.5 V input; integrated MOSFETs; 1.1 mm height | Wider VIN range and lower profile, but lower current limit restricts use to <1 W output power | Prefer for ultra-low-power IoT nodes where 2 A peak suffices and height <1.2 mm is mandatory |
Compared with TPS61088RHLR and MAX17222ATA+, the ADP1614ACPZ-1.3-R7 uniquely combines 1.3 MHz operation, 4 A programmable current limit, and 2.5 V minimum input - making it optimal for high-efficiency, space-constrained boost designs needing precise overcurrent tuning and minimal inductor volume.

FAQ
What is the exact switching frequency tolerance of ADP1614ACPZ-1.3-R7?
The ADP1614ACPZ-1.3-R7 has a guaranteed switching frequency range of 1.1 MHz to 1.4 MHz at TJ = 25°C, with typical value 1.3 MHz. This ±10% tolerance is factory-trimmed and remains stable across input voltage (2.5 V–5.5 V) and temperature (−40°C to +125°C), as confirmed in Table 1 of the Rev. B datasheet.
Can ADP1614ACPZ-1.3-R7 operate with input voltage below 2.5 V?
No. ADP1614ACPZ-1.3-R7 is specified for 2.5 V to 5.5 V input only. Below 2.5 V, undervoltage lockout activates - the device disables switching and draws only 0.25 µA. The UVLO rising threshold is 2.33 V minimum, and operation outside the rated range risks unstable regulation or failure to start.
How is the current limit set on ADP1614ACPZ-1.3-R7?
The current limit on ADP1614ACPZ-1.3-R7 is set by an external resistor (RCL) connected between Pin 9 (CLRES) and GND. For example, 61.9 kΩ yields 4 A maximum peak current at VIN = 3.6 V and VOUT = 15 V. The relationship is nonlinear and documented in Figures 10–13 of the datasheet.
Does ADP1614ACPZ-1.3-R7 require external slope compensation?
No. ADP1614ACPZ-1.3-R7 integrates slope compensation for current-mode control. It remains stable in continuous conduction mode (CCM) up to 92% duty cycle without external components, as verified in the Theory of Operation section and Figure 32 block diagram.
What is the recommended soft-start capacitor value for ADP1614ACPZ-1.3-R7?
A 68 nF capacitor on the SS pin (Pin 10) is recommended for ADP1614ACPZ-1.3-R7 to achieve ~10 ms soft-start time. The SS pin sources 5.5 µA (typical), so tSS ≈ (1.23 V × CSS) / 5.5 µA. Larger values increase ramp time but improve inrush control; smaller values risk overshoot.
