Product details

Overview

AP6015-18M10G-13 from Diodes Incorporated is a fixed-output 1.8V, 800mA synchronous step-down DC-DC converter in MSOP-10L package, operating from 2.5V to 5.5V input, delivering >94% efficiency at 300mA, with 1MHz switching frequency and 150μA quiescent current-designed for Li-ion or multi-cell alkaline/NiMH-powered portable media players and USB DSL modems.

For engineers reviewing the AP6015-18M10G-13 datasheet, AP6015-18M10G-13 pinout, AP6015-18M10G-13 application, or AP6015-18M10G-13 equivalent, key selection criteria include fixed 1.8V output accuracy (±3%), power-good open-drain signaling, internal soft-start (1ms), UVLO threshold (1.6V typ), and thermal performance (θJA = 161°C/W) in space-constrained mobile designs.

Technical Context

The AP6015-18M10G-13 implements current-mode PWM control with integrated N- and P-channel MOSFETs (R_DS(on) = 280mΩ typ each), enabling fast transient response and stable regulation across load currents from 10mA to 800mA. Its 1MHz oscillator allows compact 3.3μH inductor and 10μF ceramic output capacitor implementation.

It features an internal 0.8V reference, fixed 1.8V feedback divider, open-drain power-good output active above 92% V_OUT, and shutdown current ≤1μA. Thermal protection and cycle-by-cycle current limiting (1200–1600mA) ensure robust operation over –40°C to +85°C ambient.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 1.8V ±3% over full load/temperature range-ensures stable core voltage for low-power microcontrollers and baseband ICs.
Max Output Current	800mA continuous-supports single-core application processors and RF transceivers in portable devices.
Input Voltage Range	2.5V to 5.5V-compatible with 1-cell Li-ion (2.7–4.2V) and 2–3-cell alkaline/NiMH (2.4–4.5V) battery inputs.
Switching Frequency	1MHz typical-enables use of small 3.3μH inductors and reduces PCB footprint versus lower-frequency converters.
Quiescent Current	150μA typical-minimizes battery drain during active standby in always-on connectivity modules.
Efficiency	94% at V_IN=5V, V_OUT=3.3V, I_OUT=300mA-maximizes runtime in power-sensitive handheld applications.
UVLO Threshold	1.6V typical-prevents erratic startup during battery brownout while allowing deep discharge utilization.
Thermal Resistance	θ_JA = 161°C/W (MSOP-10L)-requires minimal copper area for thermal management in thin-profile layouts.

Pinout & Package

AP6015-18M10G-13 is housed in a thermally enhanced MSOP-10L (3.0mm × 4.9mm, 0.5mm pitch) package with exposed PGND pad for improved heat dissipation and EMI control.

Pin/Terminal	Circuit Role	Design Meaning
PVCC	Main power input	Accepts 2.5–5.5V input; requires local 10μF ceramic capacitor to minimize high-frequency ripple.
VCC	Bias supply bypass	Internal LDO input; must be decoupled with 1μF capacitor adjacent to pin for stable gate drive.
GND	Analog ground reference	Low-noise reference for error amplifier and bandgap; separated from PGND in layout for noise isolation.
PG	Power-good indicator	Open-drain output active when V_OUT ≥92% of 1.8V; requires external pull-up for system power sequencing.
FB	Feedback node	Internally connected to fixed 1.8V resistor divider; not accessible for adjustment in this variant.
CC	Compensation network	Connects external RC network (e.g., 68kΩ + 100pF) to stabilize loop response and prevent oscillation.
NC	No-connect terminal	Unbonded pin; must remain floating-no routing or soldering permitted.
EN	Enable control	Active-high logic input; drives device into <1μA shutdown when pulled low.
LX	Switching node	High-current connection to external inductor; demands short, wide copper trace to reduce EMI and losses.
PGND	Power ground return	High-current return path for MOSFETs and inductor; tied to exposed pad for thermal conduction.

Key Features

Feature	Design Value
Synchronous rectification	Integrated N- and P-channel MOSFETs eliminate external diode, raising efficiency by ~8% vs. asynchronous designs at light loads.
Current-mode PWM control	Enables precise peak-current limiting and inherent line/load transient immunity without external compensation tuning.
Internal soft-start	1ms ramp time prevents inrush current and output overshoot during power-up-critical for sensitive downstream logic.
Power-good monitoring	Open-drain PG signal provides reliable system-level power sequencing confirmation with 2.5% hysteresis.
Green packaging	MSOP-10L meets RoHS Directive 2002/95/EC with Br/Sb-free molding compound and lead-free finish.
Thermal protection	Automatic shutdown below T_J = 150°C prevents damage during sustained overload or poor heatsinking.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fixed-output synchronous buck converter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AP3428WU-7	Same manufacturer, 1.8V fixed, 1MHz, but rated for 1A output and uses WLCSP-12 package (1.35×1.35mm).	Targeted at ultra-dense wearables where MSOP-10L footprint is too large; lacks PG pin and has higher quiescent current (220μA).	Select when board space is <1.8mm² and 1A capability is required; avoid if PG sequencing or <150μA IQ is mandatory.
TPS62231DRVR	Texas Instruments part: 1.8V fixed, 800mA, 3.5MHz switching, 22μA IQ, but requires external compensation and no PG output.	Optimized for lowest IQ in always-on IoT sensors; unsuitable for systems requiring power-good handshaking or <1MHz EMI constraints.	Prefer for battery life-critical sensor nodes; reject for portable consumer devices needing PG signaling or 1MHz EMI compliance.

Compared with AP3428WU-7 and TPS62231DRVR, AP6015-18M10G-13 uniquely balances PG functionality, 150μA IQ, MSOP-10L manufacturability, and 1MHz EMI profile-making it optimal for cost-sensitive, mid-volume portable electronics where reliability and design simplicity outweigh ultra-low-IQ or ultra-small-footprint needs.

FAQ

What is the recommended input capacitor for AP6015-18M10G-13?

A minimum 10μF X5R/X7R ceramic capacitor must be placed between PVCC and GND, located as close as possible to the PVCC pin. This value ensures stable operation across the 2.5–5.5V input range and suppresses high-frequency switching noise. Larger capacitance (e.g., 22μF) improves transient response but is not required for basic functionality.

Does AP6015-18M10G-13 support adjustable output voltage?

No. The "18" suffix denotes a factory-trimmed fixed 1.8V output version. The FB pin is internally connected to a precision resistor divider and is not accessible for external adjustment. For adjustable output, select the AP6015-ADJM10G-13 variant instead.

How is the power-good (PG) signal used in system design?

The PG pin is an open-drain output that pulls low when V_OUT drops below 92% of 1.8V and floats high when valid. It requires an external pull-up resistor (typically 10–100kΩ) to VO or a system rail. PG enables safe power sequencing-e.g., releasing reset to an MCU only after stable 1.8V is confirmed.

What thermal considerations apply to MSOP-10L mounting?

The MSOP-10L package uses an exposed PGND pad for thermal conduction. Diodes recommends using ≥4 thermal vias (0.3mm diameter) connecting the pad to inner ground planes, plus ≥100mm² of 2oz copper on top/bottom layers. This achieves the specified θ_JA = 161°C/W and prevents thermal shutdown at 800mA continuous load.
