Product details
Overview
AP61100Z6-7 from Diodes Incorporated is a 1A synchronous buck converter with integrated 110mΩ high-side and 80mΩ low-side MOSFETs, operating from 2.3V to 5.5V input and delivering adjustable output (0.6V–3.6V) using constant-on-time (COT) control. It achieves up to 89% efficiency at 5mA light load, features 15μA quiescent current in PFM mode, and delivers fast transient response for FPGA/DSP core supplies.
For engineers reviewing the AP61100Z6-7 datasheet, AP61100Z6-7 pinout, AP61100Z6-7 application, or AP61100Z6-7 equivalent, key selection criteria include its SOT563 package footprint, dual-mode EN-controlled operation (PFM/PWM), power-good signaling (AP61102 variant), and thermal shutdown at +160°C - all critical for space-constrained, battery-sensitive embedded power rails.
Technical Context
The AP61100Z6-7 implements Constant On-Time (COT) control with a fixed 70ns minimum off-time and input-voltage-compensated on-time calculation (tON = VOUT / (VIN × fSW)), enabling pseudo-fixed switching frequency (1.7–2.7MHz) across input range and eliminating external compensation components.
It integrates full protection: undervoltage lockout (UVLO falling at 1.84V), VIN overvoltage protection (OVP rising at 6.3V), peak/valley current limiting (2.5A/1.9A), and thermal shutdown (+160°C with +30°C hysteresis), while supporting programmable operation mode via EN pin voltage threshold (VIN – 200mV boundary).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 2.3V to 5.5V DC - supports single-cell Li-ion, USB-powered, and 3.3V/5V distributed bus inputs without pre-regulation. |
| VOUT Range | 0.6V to 3.6V - set by external resistor divider; 0.6V ±2% reference enables precise core voltage regulation for ASICs/FPGAs. |
| IOUT Max | 1A continuous - sufficient for low-power processors, sensors, and communication ICs in compact consumer and industrial designs. |
| IQ (PFM) | 15μA typical - minimizes standby power loss in always-on battery-backed systems like smart home sensors. |
| fSW | 2.2MHz typical (VIN=5V, VOUT=1.8V) - enables use of small 1μH inductors and reduces EMI filtering burden. |
| RDS(ON) HS/L | 110mΩ / 80mΩ - low conduction loss improves full-load efficiency and thermal performance in SOT563 package. |
| Protection | UVLO (1.84V), OVP (6.3V), peak/valley current limit, thermal shutdown - ensures robust operation under fault conditions without external circuitry. |
Pinout & Package
SOT563 package: 6-pin, 1.6mm × 1.6mm × 0.55mm body, 0.5mm pitch, thermally enhanced exposed pad (connected to GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB | Feedback sensing input | Monitors output voltage via resistive divider; internal 0.6V reference sets regulation accuracy and stability. |
| GND | Power ground reference | Common return path for VIN, SW, and internal circuits; must be connected to low-impedance PCB ground plane. |
| VIN | Main power input | Supplies IC bias and power stage; requires local 10µF ceramic bypass capacitor to suppress switching noise. |
| SW | Switching node output | Drives external LC filter; connects directly to inductor; high dv/dt node requiring careful layout and clearance. |
| EN | Enable and mode control | Digital input: >0.91V enables device; voltage relative to VIN selects PFM (high) or forced PWM (low) operation. |
| OUT | Output power rail (AP61100) | Direct connection to load; not internally connected to GND; used for output sensing in AP61100 configuration (NC in AP61102). |
Key Features
| Feature | Design Value |
|---|---|
| Constant On-Time (COT) Control | Enables instantaneous load transient response (<10µs recovery) and eliminates loop compensation components for simplified design. |
| Programmable PFM/PWM Mode | EN pin voltage threshold (VIN – 200mV) allows dynamic selection between high-efficiency light-load PFM and stable heavy-load PWM. |
| Integrated Power-Good (AP61102) | Open-drain PG signal with 55µs rise delay and ±5% regulation window provides reliable system power sequencing and fault detection. |
| Low-IQ Shutdown | 0.1μA shutdown current enables ultra-low-power state retention in portable and IoT edge devices. |
| Full Protection Suite | UVLO, OVP, peak/valley current limit, and thermal shutdown operate autonomously without external supervision or firmware. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2153GQ-Z | Higher 2A rating, 3mm × 3mm QFN-12, 25μA IQ, no PG output | Better suited for higher-current loads but requires larger PCB area and lacks power-good signaling | Select when >1A output or lower thermal resistance (θJA = 45°C/W) is required; avoid if PG monitoring or SOT563 footprint is mandatory |
| TI TPS62231DRVR | 1A, 2.05V–6V input, 17μA IQ, 2.25MHz, no OVP/valley current limit | Lacks VIN overvoltage and valley current protection; uses different enable logic (active-high, no mode selection) | Choose for TI ecosystem compatibility or where OVP is handled upstream; not recommended for unregulated 5V bus applications |
Compared with MP2153GQ-Z and TPS62231DRVR, AP61100Z6-7 uniquely combines SOT563 miniaturization, integrated OVP/valley current limit, and EN-programmable PFM/PWM - making it optimal for cost-sensitive, space-constrained, and safety-critical 1A point-of-load designs.

FAQ
What is the difference between AP61100Z6-7 and AP61102?
AP61100Z6-7 is the AP61100 variant with an OUT pin for direct output connection, while AP61102 substitutes that pin with an open-drain Power-Good (PG) output. Both share identical electrical specs, package, and control architecture; the choice depends on whether system-level power sequencing (PG) or direct output routing (OUT) is required.
Can AP61100Z6-7 operate with a 1.8V input?
No. The absolute minimum input voltage is 2.3V per datasheet specifications, and undervoltage lockout disables operation below 1.84V. Attempting 1.8V operation will prevent startup and may cause erratic behavior due to insufficient gate drive for the internal MOSFETs.
How is output voltage set, and what tolerance applies?
VOUT is set by a resistor divider from output to FB pin, using the internal 0.6V ±2% reference. For example, R1=200kΩ and R2=100kΩ yields 1.8V (VOUT = 0.6V × (1 + R1/R2)). Total output tolerance includes reference error, resistor ratio error, and load/line regulation - typically ±3% over temperature and line.
Does AP61100Z6-7 require an external soft-start capacitor?
No. It features an internal 0.5ms soft-start timer that ramps the output voltage linearly to prevent inrush current and overshoot. No external capacitor is needed, simplifying BOM and reducing footprint - a key advantage over many competing buck controllers.
