Product details
Overview
AP72250CJ12-EVM from Diodes Incorporated is an evaluation module for the AP72250 synchronous boost converter IC, designed to demonstrate 0.6V–5.5V input operation with 4.7A switching current, 900kHz fixed-frequency PWM control, and selectable PFM/USM/FPWM modes. It supports output voltages from 1.7V to 5.5V and features integrated 20mΩ high-side and 26mΩ low-side MOSFETs in a 1.75mm × 1.35mm WLCSP package - used for validating power delivery in ultra-compact portable power banks and USB supply designs.
For engineers reviewing the AP72250CJ12-EVM datasheet, AP72250CJ12-EVM pinout, AP72250CJ12-EVM application, or AP72250CJ12-EVM equivalent, this module enables rapid validation of startup behavior at 1V VIN, load transient response under 2A step changes, efficiency mapping across light-load PFM and full-load FPWM, and seamless pass-through mode transitions in battery-powered systems.
Technical Context
The AP72250CJ12-EVM implements peak current mode control with internal 900kHz oscillator, slope compensation (SE), and dual-MOSFET gate drivers optimized for low-RDS(ON) switching. Its functional block includes error amplifier, COMP node comparator, CSA current-sense amplifier, and thermal shutdown circuitry tied to the AP72250 IC's 12-ball WLCSP footprint.
It validates real-world performance of the AP72250's three operating modes: PFM (20μA IQ), USM (25kHz ultrasonic switching), and FPWM (forced 900kHz), each with distinct VOUT ripple, efficiency vs. load, and soft-start timing characteristics confirmed in Figures 14–54 of DS44135 Rev. 1–2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.6V to 5.5V DC - supports single-cell LiFePO₄, NiMH, and supercapacitor sources without external LDO pre-bias. |
| Output Voltage Range | 1.7V to 5.5V - programmable via FB resistive divider; enables USB 5V, 3.3V logic rails, or custom intermediate rails. |
| Switching Current | 4.7A peak - sustains 2A continuous output with <200mV ripple at 50mA–2A load steps per Figure 24–26. |
| Quiescent Current | 20μA in PFM - extends battery runtime in always-on sensor nodes powered by coin cells or energy harvesters. |
| Switching Frequency | 900kHz nominal (CCM), 25kHz in USM - balances EMI suppression (USM) and inductor size reduction (PWM). |
| Efficiency | 89% at 5mA load (VIN=3.6V, VOUT=5.2V) - minimizes no-load power loss in standby-critical wearables. |
| Protection Features | UVLO (0.44–0.70V), thermal shutdown (+150°C), SCP, valley current limit (−2.0A), and PG open-drain indicator - ensures robustness during cold-start and short-circuit events. |

FAQ
What is the minimum input voltage required to start up the AP72250CJ12-EVM?
The AP72250CJ12-EVM demonstrates the AP72250 IC's 1.0V minimum startup voltage under load, verified per Figure 10 in DS44135. Below 1.0V, the device remains in UVLO until VIN rises above the rising POR threshold (1.0–1.1V). Startup is enabled only when EN is high and VIN exceeds this threshold - no external bias is needed.
How does the MODE pin configure operating modes on the AP72250CJ12-EVM?
The MODE pin selects between PFM (MODE = GND), USM (MODE floating), and FPWM (MODE = VIN). Each setting alters switching frequency, quiescent current, and ripple: PFM delivers 20μA IQ but variable frequency; USM fixes ~25kHz to avoid audible noise; FPWM locks at 900kHz for predictable EMI filtering. Pin states are validated in Figures 18, 31, and 45.
Can the AP72250CJ12-EVM support output voltages below 1.7V?
No. The AP72250 IC has a hard-limited 1.7V minimum VOUT due to internal reference and error amplifier architecture, as specified in Recommended Operating Conditions (Section 5). Attempting lower outputs violates regulation accuracy and may cause instability - the evaluation module reflects this absolute boundary.
What is the purpose of the PG (Power-Good) signal on the AP72250CJ12-EVM?
The PG pin provides an open-drain status signal with 5MΩ internal pull-up. It asserts low when VOUT falls below 75% or rises above 120% of target (per Table 6), including during soft-start. This enables system-level fault detection and sequencing - e.g., enabling downstream regulators only after PG goes high, as shown in Figure 10's startup waveform.
