Product details
Overview
NCV6336BMFCCT1G from onsemi is an automotive-grade synchronous buck converter designed as a transient load helper in multi-rail power systems for portable and infotainment applications. It delivers up to 5.0 A output current, supports I²C-configurable output voltage from 0.6 V to 1.4 V in 6.25 mV steps, operates at 2.74 MHz switching frequency, and integrates high-side (23 mΩ) and low-side (12 mΩ) MOSFETs - enabling compact 330 nH inductor + 47 µF capacitor solutions in smartphones and ADAS domain controllers.
For engineers reviewing the NCV6336BMFCCT1G datasheet, pinout, applications, or equivalent options, key selection considerations include its AEC-Q100 qualification, dual-mode PWM/PFM operation with <35 µA quiescent current in PFM, thermal warning/interrupt signaling (105 °C pre-warning, 135 °C warning, 150 °C shutdown), active output discharge, and support for dynamic voltage scaling via I²C up to 3.4 MHz.
Technical Context
The NCV6336BMFCCT1G implements voltage-mode control with integrated error amplifier and fully internal compensation. Its dual operating modes - forced PWM for tight regulation and auto PFM for ultra-low-light-load efficiency - are selected either by hardware (VSEL pin) or register programming (PWMVSEL0/1 bits), with seamless transitions governed by inductor current mode detection (CCM/DCM boundary).
It features three independent thermal thresholds (pre-warning at 105 °C, warning at 135 °C, shutdown at 150 °C), each generating dedicated interrupts via INTB; programmable peak current limiting (IPEAK[1..0] sets 5.2–6.8 A); and configurable power-up delay (DELAY[2..0], 2.2 ms resolution) and DVS ramp rate (DVS[1..0]). All digital interfaces - EN, VSEL, SCL, SDA, PG, INTB - include internal pull-down resistors and ESD protection (2.5 kV HBM).

Pinout & Package
NCV6336BMFCCT1G uses a 20-pin WLCSP (Wafer Level Chip Scale Package), case 568AG, measuring 2.0 mm × 1.6 mm with 0.4 mm pitch. The package integrates power and signal terminals in a compact, low-profile layout optimized for space-constrained mobile and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AVIN | Analog Supply Input | Provides analog/digital bias for internal circuitry; must be decoupled with 1.0 µF ceramic capacitor near pin. |
| PVIN (D1, D2, E1, E2) | Power Input (x4) | High-current input node for switcher; requires 4.7 µF ceramic capacitor placed adjacent to pins with short, heavy traces. |
| SW (D3, D4, E3, E4) | Switch Node Output (x4) | Drives external inductor; all four pins carry high di/dt switching current and must be routed with minimal loop area. |
| PGND (C1–C4, B3, B2) | Power Ground (x6) | High-current return path for switcher; requires local ground plane connecting all PGND pins before single-point tie to AGND. |
| FB | Feedback Input | Connects directly to output capacitor positive terminal (not plane) for accurate voltage regulation sensing. |
| EN | Enable Control | Active-high logic input with internal pull-down; initiates power-up sequence on rising edge. |
| VSEL | Configuration Select | Dual-function pin: selects between PROGVSEL0/PROGVSEL1 registers for voltage/enable/mode settings; internal pull-down. |
| SCL / SDA | I²C Interface | Standard bidirectional I²C bus interface (SCL clock, SDA data); supports up to 3.4 MHz operation and DVS commands. |
| PG / INTB | Open-Drain Outputs | PG indicates regulated output status; INTB signals thermal/warning/shutdown events - both require external pull-ups. |
| AGND | Analog Ground | Reference ground for feedback and analog blocks; must connect to system ground at single point with PGND. |
Key Features
| Feature | Design Value |
|---|---|
| Transient Load Helper Function | Shares output rail with another DC-DC without sinking current - dynamically supplies peak current surges while primary regulator handles steady-state load. |
| Configurable Peak Current Limit | Four selectable inductor peak current levels (5.2/5.8/6.2/6.8 A) via I²C LIMCONF register - matches inductor saturation rating and avoids core saturation. |
| Dynamic Voltage Scaling (DVS) | Smooth, software-controlled output voltage transitions with programmable dV/dt - eliminates processor brownouts during frequency scaling. |
| Multi-Threshold Thermal Management | Three independent die temperature thresholds (105 °C pre-warning, 135 °C warning, 150 °C shutdown) with interrupt outputs - enables proactive thermal mitigation in real time. |
| Active Output Discharge | Internally controlled discharge path (enabled by default) - ensures rapid rail collapse (<100 µs) when disabled, preventing unintended device wake-up. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4436GL-AEC1 | 4.5 A max output, fixed 2.2 MHz fSW, no I²C interface, only GPIO-based configuration. | Lacks DVS, thermal interrupts, and transient helper functionality - suitable for static-voltage rails only. | Select when cost-sensitive designs require AEC-Q100 compliance without dynamic control needs. |
| TPS6286418RTER | 6 A output, 4 MHz fSW, I²C interface, but rated only for industrial temp (−40 °C to 125 °C), not AEC-Q100. | No automotive qualification or thermal warning interrupts - limited to non-safety-critical subsystems. | Select when higher current and faster switching are prioritized over automotive certification and thermal intelligence. |
Compared with MPQ4436GL-AEC1 and TPS6286418RTER, the NCV6336BMFCCT1G uniquely combines AEC-Q100 qualification, I²C-based DVS, triple thermal thresholds with interrupt outputs, and explicit transient load helper architecture - making it the only option qualified for safety-aware, dynamically scaled automotive SoC rails.

FAQ
What is the maximum output current capability of the NCV6336BMFCCT1G?
The NCV6336BMFCCT1G delivers up to 5.0 A output current when configured with IPEAK[1..0] = 11, corresponding to a 6.8 A inductor peak current limit. This rating is validated across −40 °C to +125 °C ambient and supports transient load helper operation alongside a primary DC-DC converter on the same output rail.
Does the NCV6336BMFCCT1G support dynamic voltage scaling (DVS)?
Yes, the NCV6336BMFCCT1G supports full dynamic voltage scaling via its I²C interface or hardware VSEL pin toggle. DVS transitions are smooth and programmable - dV/dt is set by DVS[1..0] bits in the TIME register, and voltage changes can be initiated in <100 µs using the VSEL pin, bypassing I²C latency for critical timing paths.
What thermal protection features does the NCV6336BMFCCT1G provide?
The NCV6336BMFCCT1G implements three-tier thermal monitoring: pre-warning at 105 °C, warning at 135 °C, and shutdown at 150 °C (typical), each generating dedicated open-drain interrupt signals on the INTB pin. Hysteresis values (6 °C, 15 °C, and 30 °C respectively) prevent oscillation during thermal recovery.
Is the NCV6336BMFCCT1G pin-compatible with other members of the NCV6336 family?
No - the NCV6336BMFCCT1G is a specific variant within the NCV6336 family and shares the same WLCSP-20 package and pinout as NCV6336C variants, but differs in factory-programmed default configurations (e.g., I²C address, default VOUT, and thermal thresholds). Pin compatibility exists across BM/C suffixes, but register defaults and qualification level (NCV prefix = AEC-Q100) are unique to NCV6336BMFCCT1G.
What is the purpose of the transient load helper function in the NCV6336BMFCCT1G?
The transient load helper function allows the NCV6336BMFCCT1G to share an output rail with another DC-DC converter and supply only the instantaneous current surges - without sinking current - thereby improving overall system efficiency and transient response. It is especially valuable in SoC power domains where peak currents exceed the steady-state capability of the primary regulator.
How is output voltage programmed on the NCV6336BMFCCT1G?
Output voltage on the NCV6336BMFCCT1G is programmed in 6.25 mV steps from 0.6 V to 1.4 V using two 7-bit registers (PROGVSEL0 and PROGVSEL1). Selection between them is determined by the VSEL pin state and VSELGT bit. Voltage can be set at startup via VSEL or updated dynamically via I²C - enabling both static configuration and real-time DVS.
