Product details
Overview
AP72250CJ12-7 from Diodes Incorporated is a fully integrated synchronous boost DC-DC converter with 0.6V–5.5V input range, 1.7V–5.5V programmable output, 4.7A switching current capability, 900kHz fixed-frequency operation, and selectable PFM/USM/FPWM modes. It delivers high-efficiency step-up conversion in ultra-compact WLCSP packaging for space-constrained portable power systems.
For engineers reviewing the AP72250CJ12-7 datasheet, AP72250CJ12-7 pinout, AP72250CJ12-7 application, or AP72250CJ12-7 equivalent, key selection criteria include minimum 1V startup voltage, 20mΩ/26mΩ integrated high-side/low-side MOSFETs, 0.8V ±1% reference accuracy, 20μA quiescent current in PFM mode, and seamless boost-to-pass-through transition behavior.
Technical Context
The AP72250 employs fixed-frequency peak current mode control with internal slope compensation to stabilize loop dynamics across wide input-output ratios. Its dual-MOSFET architecture integrates a 20mΩ high-side and 26mΩ low-side switch, enabling efficient power delivery without external FETs.
Three user-selectable operating modes-Pulse Frequency Modulation (PFM), Ultrasonic Mode (USM), and Forced PWM-allow optimization of efficiency, noise, and transient response. The device features a precision 0.8V feedback reference, 5MΩ internal pull-up on the open-drain PG pin, and comprehensive protection including UVLO, peak/valley current limiting, SCP, and thermal shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 0.6V to 5.5V DC - supports single-cell Li-ion, NiMH, alkaline, and supercapacitor inputs. |
| VOUT Range | 1.7V to 5.5V - set via external resistor divider on FB pin; enables USB 5V, 3.3V logic, or custom rail generation. |
| Switching Current | 4.7A typical - defines maximum sustainable inductor current before peak current limit activates. |
| fSW | 900kHz nominal (±13%) - enables use of small 1µH inductors and compact ceramic output capacitors. |
| IQ (PFM) | 20μA - minimizes no-load power loss in battery-powered devices during standby. |
| RDS(ON) HS/Low-Side | 20mΩ / 26mΩ - directly determines conduction losses and thermal rise at full load. |
| VFB Accuracy | 0.800V ±1% - ensures tight output regulation tolerance independent of temperature and line/load variation. |
| Startup Voltage | 1.0V min - allows reliable start-up from deeply discharged single-cell batteries or supercapacitors. |
Pinout & Package
AP72250CJ12-7 uses the X1-WLB1713-12 wafer-level chip-scale package (1.75mm × 1.35mm, 0.4mm pitch), optimized for minimal PCB footprint and thermal performance (θJA = 90°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (A1, A2) | Output power rail | High-current output node connected to load and output capacitor; dual-ball configuration reduces IR drop. |
| GND (A3) | Analog ground reference | Reference for internal error amplifier and control circuitry; must be separated from PGND in layout. |
| FB (A4) | Feedback sensing input | Monitors resistive divider ratio to regulate VOUT; high-impedance input minimizes divider current error. |
| SW (B1, B2) | Switching node | Connection point for inductor; carries high di/dt; requires short, low-inductance routing to minimize EMI. |
| MODE (B3) | Operation mode select | Logic-controlled input: GND = PFM, floating = USM, VIN = FPWM - configures efficiency/noise trade-off. |
| PG (B4) | Power-good indicator | Open-drain output with 5MΩ internal pull-up; asserts low when VOUT deviates >20% from target. |
| PGND (C1, C2) | Power ground return | Low-impedance path for high-switching-current return; must be tied to thermal pad and bulk input cap. |
| VIN (C3) | Main power input | Supplies IC bias and switching FETs; requires local 10µF ceramic bypass capacitor near pin. |
| EN (C4) | Enable control input | Active-high digital enable; internally pulled up; floating or tied to VIN enables automatic startup. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 20mΩ HS / 26mΩ LS MOSFETs | Eliminates need for external power switches, reducing BOM count and layout complexity in portable designs. |
| 1V Minimum Startup Voltage | Enables operation from partially depleted energy sources such as supercapacitors or single-cell batteries down to 1.0V. |
| Selectably Optimized Operating Modes | PFM maximizes light-load efficiency; USM avoids audible noise; FPWM ensures constant frequency for EMI filtering. |
| Seamless Boost-to-Pass-Through Transition | Automatically bypasses boost stage when VIN ≥ VOUT – dropout, improving efficiency and reducing heat at high input voltages. |
| Comprehensive Protection Suite | Includes UVLO, peak/valley current limits, output short-circuit protection, and thermal shutdown with 20°C hysteresis. |
| Power-Good Output with Internal Pull-Up | Provides system-level power sequencing and fault monitoring without external components; simplifies host MCU interface. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS610992RTER | Lower 1.8A max switch current; 0.7V min VIN; 1.2MHz fSW; no USM mode. | Better suited for sub-1A loads with tighter board area constraints; lacks ultrasonic noise suppression. | Choose for cost-sensitive, lower-current applications where 20kHz+ switching noise is acceptable. |
| MAX77818EWL+ | Higher integration (buck-boost + charger); 5.5V max VOUT; 3.5A switch; I²C programmable. | Targeted at complex PMIC systems requiring battery charging and multiple rails-not a direct drop-in replacement. | Choose only when system requires integrated charging, fuel gauging, or multi-rail sequencing beyond simple boost. |
Compared with TPS610992RTER and MAX77818EWL+, the AP72250CJ12-7 uniquely balances 4.7A current capability, 1V startup, ultrasonic mode, and ultra-small WLCSP footprint-making it optimal for high-current, noise-sensitive, space-constrained portable power designs where discrete PMIC functionality is unnecessary.

FAQ
What is the minimum input voltage required to start up the AP72250CJ12-7?
The AP72250CJ12-7 has a guaranteed minimum startup voltage of 1.0V, allowing reliable initialization from nearly depleted single-cell batteries or supercapacitors. This threshold is distinct from its operational input range (0.6V–5.5V), which applies after startup. The POR rising threshold is specified at 1.0V to 1.1V, and UVLO falling threshold is 0.44V to 0.57V, ensuring controlled shutdown during deep discharge.
How does the MODE pin configure operating modes, and what are the practical implications?
The MODE pin selects between three modes: grounding it enables PFM for best light-load efficiency; leaving it floating activates Ultrasonic Mode (USM) to suppress audible noise by keeping switching frequency below 20kHz; connecting it to VIN forces FPWM for constant-frequency operation and predictable EMI. Each mode affects quiescent current (20μA/200μA/15mA), ripple, and transient response-requiring trade-offs based on application priorities.
Can the AP72250CJ12-7 operate without an external inductor?
No-the AP72250CJ12-7 requires an external inductor connected between SW and VIN to store and transfer energy during boost operation. The recommended value is 1µH, selected to match the 900kHz switching frequency and achieve optimal efficiency and transient response. Omitting the inductor prevents proper operation and may damage the internal MOSFETs due to uncontrolled current slew rates.
What is the function of the PG (Power-Good) pin, and how should it be interfaced?
The PG pin is an open-drain output that pulls low when VOUT falls below 75% or rises above 120% of its regulated value, or during soft-start. It includes a 5MΩ internal pull-up resistor, so no external pull-up is needed. Connect PG directly to a GPIO interrupt pin on a host MCU to trigger fault handling, or use it for power sequencing in multi-rail systems. Rise/fall delays are 2ms and 5μs respectively, supporting robust glitch immunity.
