Product details

Overview

AP62150Z6-7 from Diodes Incorporated is a 1.5A synchronous buck converter with 4.2V–18V input range, integrated 90mΩ high-side and 65mΩ low-side MOSFETs, 1.3MHz switching frequency (VIN=12V, VOUT=5V), 0.8V ±1% reference voltage, and 135μA quiescent current in PFM mode-designed for EMI-sensitive 5V/12V point-of-load supplies in flat-panel TVs and home audio systems.

For engineers reviewing the AP62150Z6-7 datasheet, AP62150Z6-7 pinout, AP62150Z6-7 application, or AP62150Z6-7 equivalent, key selection considerations include its COT control architecture for fast transient response, proprietary gate driver for ringing-free SW node, cycle-by-cycle valley current limit at 2.8A typ, and dual-package availability (SOT563/TSOT26) with validated thermal performance up to +125°C ambient.

Technical Context

The AP62150Z6-7 implements Constant On-Time (COT) control with input-voltage–compensated on-time calculation (t_ON = V_OUT/(V_IN × f_SW)), enabling pseudo-fixed-frequency operation across 4.2–18V input while maintaining fast load-step response. Its multi-level gate driver suppresses SW node ringing without degrading rise/fall times, directly reducing high-frequency radiated EMI.

Protection includes undervoltage lockout (UVLO falling threshold 3.6V), thermal shutdown at +160°C with +20°C hysteresis, and valley-current limiting via low-side MOSFET conduction sensing-triggering hiccup mode after 2.5ms sustained overcurrent. Soft-start time is fixed at 2.5ms to limit inrush current.

Key Specifications

Parameter	Value and Actual Design Meaning
VIN Range	4.2V to 18V DC - supports direct connection to 5V/12V distributed bus rails without pre-regulation
Output Current	1.5A continuous - sufficient for FPGA core, DSP I/O, or ASIC auxiliary rail power delivery
fSW	1.3MHz typical (VIN=12V, VOUT=5V) - enables compact LC filter design with ≤3.3μH inductors
IQ	135μA in PFM mode - extends battery runtime in always-on consumer electronics standby states
VFB Accuracy	0.800V ±1% at TA=+25°C - ensures ±1.6% output voltage tolerance over full temperature and line/load range
RDS(ON) HS/LS	90mΩ / 65mΩ - minimizes conduction loss at 1.5A, supporting >90% peak efficiency at mid-load
EN Threshold	1.20V logic-high, 1.10V logic-low - allows precise power sequencing using resistor dividers or microcontroller GPIO

Pinout & Package

AP62150Z6-7 is packaged in TSOT26 (Standard), a 6-pin, 1.6mm × 2.9mm, 0.95mm height surface-mount package with exposed thermal pad. Pin mapping is verified per Diodes DS42700 Rev. 3-2 Figure 1 (top view).

Pin/Terminal	Circuit Role	Design Meaning
VIN (Pin 3)	Power Input	Supplies IC bias and high/low-side MOSFETs; requires ≥10μF ceramic bypass to GND near pin
SW (Pin 2)	Switch Node	Connects to inductor input; high di/dt node requiring tight layout and ground plane clearance
GND (Pin 1)	Power Ground	Primary return path for VIN, SW, BST, and FB; must be low-impedance copper pour under IC
BST (Pin 6)	Bootstrap Supply	Drives high-side MOSFET gate; requires 100nF ceramic capacitor between BST and SW
EN (Pin 5)	Enable Control	Active-high digital input; internal 1.5μA pull-up enables auto-start when floating
FB (Pin 4)	Feedback Sense	Resistive divider midpoint; sets VOUT = 0.8V × (1 + R1/R2); high-impedance input

Key Features

Feature	Design Value
EMI-optimized switching	Proprietary multi-level gate driver eliminates SW node ringing while preserving <10ns rise/fall times
COT control architecture	Enables stable loop compensation with only two external components (R1/R2) and no compensation network
Valley current limiting	Detects overcurrent during low-side conduction phase, triggering immediate cycle termination at 2.8A typ
Thermal protection	Shuts down at TJ = +160°C and auto-restarts at +140°C, preventing permanent silicon damage under overload
UVLO programmability	EN pin's 5.5μA hysteresis current source allows external resistor divider to set custom VIN turn-on/off thresholds

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MP2451DT-LF-Z	Fixed 2.2MHz fSW, no programmable UVLO, higher IQ (250μA), same 1.5A rating and 4.5–18V VIN	Lacks COT control and EMI-optimized gate drive; less suitable for noise-sensitive audio or fast-transient FPGA loads	Select when board space demands smaller inductors and EMI requirements are relaxed
TPS561201DRCT	Adaptive COT control, 1.5A, 4.5–17V VIN, but larger SOT23-6 package and no BST pin (integrated bootstrap)	Higher thermal resistance (θJA = 120°C/W) limits ambient operating range; no external UVLO adjustment	Prefer for designs prioritizing ease of layout over thermal density or sequencing flexibility

Compared with MP2451DT-LF-Z and TPS561201DRCT, AP62150Z6-7 uniquely combines COT stability, EMI-suppressed switching, and field-programmable UVLO in a thermally efficient TSOT26 package-making it optimal for compact, noise-critical, and sequenced power systems.

FAQ

What is the maximum recommended ambient temperature for continuous 1.5A operation in TSOT26 package?

The AP62150Z6-7 supports continuous 1.5A output at +85°C ambient temperature when mounted on a standard 2-layer FR-4 PCB with minimum recommended copper area. Thermal derating begins above this point, with full 1.5A capability maintained up to +70°C ambient on typical layouts; junction temperature must not exceed +125°C operating limit.

Can the output voltage be adjusted below 0.8V using external resistors?

No-the AP62150Z6-7 has a fixed 0.8V internal reference voltage and is not designed for sub-0.8V operation. The feedback divider sets VOUT = 0.8V × (1 + R1/R2), so minimum achievable output is 0.8V (when R1 = 0Ω and R2 = open). Attempting lower outputs violates regulation accuracy and may cause instability or overvoltage under light load.

Does AP62150Z6-7 support forced PWM mode, or is it limited to auto PFM/PWM?

The AP62150Z6-7 operates exclusively in automatic PFM/PWM mode-no external pin or register enables forced PWM. At light loads, it seamlessly transitions to PFM to maintain high efficiency (135μA IQ), and reverts to CCM at higher loads. This behavior is inherent to its COT architecture and cannot be overridden.

How is the BST capacitor value determined, and what happens if it's undersized?

A 100nF X7R ceramic capacitor is required between BST and SW to sustain high-side gate drive voltage. If undersized, insufficient charge storage causes high-side MOSFET turn-off during heavy load, resulting in output droop, increased ripple, and potential thermal stress. Layout must minimize trace inductance between BST/SW pins and capacitor pads.
