Product details
Overview
The MAXM17536ALY# from Maxim Integrated is a fully integrated, high-efficiency synchronous step-down SiP power module delivering up to 4A continuous output current, operating from 4.5V to 60V input, with adjustable output voltage from 0.9V to 12V, and featuring peak-current-mode control for FPGA and DSP point-of-load regulation.
For engineers reviewing the MAXM17536ALY# datasheet, MAXM17536ALY# pinout, MAXM17536ALY# application, or MAXM17536ALY# equivalent, this page provides verified technical context, validated pin functions, confirmed thermal and EMI performance per CISPR22 Class B, and real-world efficiency curves across PWM/DCM/PFM modes at multiple VOUT and load conditions.
Technical Context
The MAXM17536ALY# implements a peak-current-mode controller with internal transconductance error amplifier, slope compensation, and dual integrated n-channel MOSFETs. It supports three distinct operating modes-PWM (constant frequency, negative inductor current allowed), PFM (pulse-skipping, ultra-low IQ = 128μA), and DCM (no pulse skipping, no negative current)-selected via the MODE/SYNC pin at power-up.
It integrates a thermally optimized 29-pin SiP package with embedded 4.7μH shielded inductor, full compensation network, and dual LDOs (INLDO and EXTVCC switchover). The device features programmable soft-start (via SS capacitor), adjustable switching frequency (100kHz–2.2MHz via RT resistor), and robust protection including hiccup-mode overload, thermal shutdown (165°C), and RESET monitoring with 92.5%–97.7% VOUT thresholds.
Key Specifications

Pinout & Package
MAXM17536ALY# uses a compact, thermally enhanced 29-pin system-in-package (SiP) measuring 9mm × 15mm × 4.32mm. The package integrates shielding, inductor, MOSFETs, and compensation components, requiring only external input/output capacitors and feedback resistors for full operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | 5V LDO output | Internally bypassed; no external connection permitted - powers internal logic and gate drivers. |
| RESET (Pin 2) | Open-drain fault indicator | Asserts low when FB falls below 92.5% of setpoint; deasserts after 1024 cycles once FB rises above 95.5% - enables system-level power sequencing and monitoring. |
| RT (Pin 3) | Frequency programming node | Resistor-to-SGND sets fSW; open = 450kHz default - allows precise EMI tuning and inductor size optimization. |
| SGND (Pin 4) | Analog reference ground | Separate from PGND to minimize noise coupling into feedback and compensation paths - critical for stable loop response. |
| CF (Pin 5) | Compensation node | Connects 2.2pF capacitor to FB - completes Type II compensation network; eliminates need for external op-amp or RC networks. |
| FB (Pin 6) | Feedback input | Monitors output via resistor divider; regulates VOUT to 0.9V reference with ±1.5% accuracy across temperature - enables precision point-of-load regulation. |
| SS (Pin 7) | Soft-start timing input | Capacitor-to-SGND sets ramp time - prevents inrush current and ensures controlled startup into heavy or pre-biased loads. |
| EN/UVLO (Pin 8) | Enable and input undervoltage lockout | Resistor divider sets turn-on threshold (1.215V typ); open = enabled - supports system-level power sequencing and brownout protection. |
| IN (Pins 9, 28) | Main power input | High-current path for 4.5V–60V input; requires local 4×4.7µF ceramic decoupling - minimizes input ripple and improves transient response. |
| PGND (Pins 10, 14–21, 27) | Power ground return | Multiple low-inductance connections to thermal pad - reduces ground bounce and improves thermal dissipation under full 4A load. |
| EXTVCC (Pin 11) | External bias input | Accepts 4.84V–24V to bypass internal LDO - improves efficiency by >2% at high input voltages (e.g., 48V bus). |
| BST (Pin 12) | Bootstrap capacitor node | Internally connected to LX via 0.1µF capacitor - supplies gate drive for high-side MOSFET; no external components allowed. |
| LX (Pin 13) | Switching node | Internal connection between MOSFETs and inductor - unconnected externally; critical for EMI control and layout integrity. |
| OUT (Pins 22–25) | Regulated output | Four parallel pins reduce resistance/inductance - delivers up to 4A with minimal IR drop and improved thermal spreading. |
| DL (Pin 26) | Low-side gate driver output | Drives internal low-side MOSFET; no external access - ensures optimal dead-time control and shoot-through prevention. |
| MODE/SYNC (Pin 29) | Mode selection and clock sync | Configures PWM/DCM/PFM at power-up; also accepts external 100kHz–2.2MHz clock - enables synchronized multi-rail systems. |
| EP1/EP2/EP3 | Exposed thermal pads | Internally shorted to PGND/SGND - must be soldered to large copper pour for θJA = 24°C/W performance and 150°C junction rating. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated shielded inductor | Eliminates external magnetics and EMI shielding - reduces solution footprint by >50% versus discrete buck controllers. |
| Three selectable control modes | PWM (constant fSW, best light-load stability), PFM (128μA IQ, best light-load efficiency), DCM (mid-point tradeoff) - configurable without firmware. |
| Programmable soft-start | Capacitor-adjustable ramp time prevents inrush into large output capacitance or pre-biased rails - avoids system reset during startup. |
| Integrated thermal and fault protection | Hiccup-mode overload, 165°C thermal shutdown with 10°C hysteresis, and RESET output with 92.5%/97.7% trip/de-trip thresholds - enables autonomous fault recovery. |
| CISPR22 Class B compliance | Verified with standard filter components (C18–C22 = 4.7µF, L1 = 8.2µH) - meets radiated/conducted emission limits without custom filtering. |
| EXTVCC switchover LDO | Automatically selects between INLDO and EXTVCC inputs - improves efficiency by >2% at VIN > 24V while maintaining 5V VCC regulation. |

The MAXM17536ALY# delivers up to 4A continuous output current across its full operating temperature range (–40°C to +125°C ambient), verified with standard PCB layout and thermal management per datasheet guidelines. Derating applies above 85°C ambient; output current vs. temperature curves confirm 4A capability at 70°C ambient with 4-layer board cooling.
Does the MAXM17536ALY# require external compensation components?
No, the MAXM17536ALY# integrates full Type II compensation, requiring only a 2.2pF capacitor between CF and FB pins. No external op-amp, resistors, or additional capacitors are needed - simplifying design and eliminating loop-tuning iterations typically required with discrete controllers.
How does the MODE/SYNC pin configure operating modes on the MAXM17536ALY#?
The MAXM17536ALY# latches the MODE/SYNC pin state at power-up: open = PFM mode (ultra-low IQ), grounded = PWM mode (constant frequency), tied to VCC = DCM mode (no pulse skipping, no negative current). Mode changes during operation are ignored - ensuring deterministic behavior in dynamic load environments.
Can the MAXM17536ALY# operate with an external clock source?
Yes, the MODE/SYNC pin accepts an external clock signal from 100kHz to 2.2MHz for synchronization. The device captures frequencies within ±40% of its internal fSW set by RT, enabling noise reduction in multi-rail systems and EMI spread-spectrum alignment without modifying internal timing.
What thermal management is required for the MAXM17536ALY# at full 4A load?
At 4A continuous load, the MAXM17536ALY# requires connection of EP1/EP2/EP3 thermal pads to a minimum 400mm² copper pour tied to PGND/SGND. With this, θJA = 24°C/W is achieved on a 4-layer board; junction temperature remains below 150°C at 125°C ambient when VIN = 24V and VOUT = 5V.
