Product details
Overview
NCP6922CCMTTXG from onsemi is a mini-power management IC integrating two 800 mA step-down DC-DC converters with dynamic voltage scaling (DVS) and two 150 mA low-noise LDOs, all controlled via I²C interface; operates from 2.3 V to 5.5 V input, delivers 1.2 V typical output from DC-DCs, and targets camera modules and microprocessor subsystems in battery-powered portable devices.
For engineers reviewing the NCP6922CCMTTXG datasheet, pinout, applications, or equivalent options, key selection criteria include I²C-programmable DVS capability, 95% peak DC-DC efficiency at 3 MHz switching frequency, ultra-low 82 µA quiescent current, 50 µVrms LDO output noise, and WQFN-20 package compatibility with space-constrained mobile PCB layouts.
Technical Context
The NCP6922CCMTTXG implements voltage-mode control for both DC-DC converters, supporting independent I²C-based output voltage programming across 0.6 V–3.3 V in 12.5 mV steps and enabling dynamic core voltage adjustment for processors. Each converter delivers up to 800 mA with 3 MHz fixed-frequency operation and 95% peak efficiency.
Its dual LDOs provide 1.0 V–3.3 V programmability in 50 mV steps, deliver 150 mA each, and achieve 50 µVrms output noise-critical for analog-sensitive camera and audio subsystems-while drawing only 82 µA quiescent current in full operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-rail PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65136RTER | Single 800 mA buck + dual 200 mA LDOs; no DVS; SPI interface only | Lacks I²C and dynamic voltage scaling - unsuitable for processor core scaling | Select when fixed-voltage, non-DVS multi-rail supply suffices and SPI is preferred |
| RTQ2132B-WE | Dual 1 A buck + dual 300 mA LDOs; 2.7–5.5 V input; I²C; higher current but larger 5×5 mm QFN-32 | Higher output capability and pin count - requires PCB redesign and layout revalidation | Select when >800 mA per DC-DC or >150 mA per LDO is required and board space allows |
Compared with TPS65136RTER and RTQ2132B-WE, the NCP6922CCMTTXG uniquely balances I²C-based DVS, ultra-low IQ, and 4×4 mm footprint-making it optimal for space- and battery-life-constrained camera and mobile processor subsystems where fine-grained voltage control is mandatory.

FAQ
What is the input voltage range supported by the NCP6922CCMTTXG?
The NCP6922CCMTTXG supports an input voltage range of 2.3 V to 5.5 V, enabling direct connection to single-cell lithium-ion batteries (2.7–4.2 V) and standard USB 5 V sources. This range accommodates common portable power architectures without requiring pre-regulation, and the device maintains regulation stability across the full span - critical for maintaining camera sensor and processor functionality during battery discharge.
Does the NCP6922CCMTTXG support dynamic voltage scaling (DVS) for both DC-DC converters?
Yes, the NCP6922CCMTTXG supports independent DVS for both DC-DC converters via its I²C interface, with output voltage programmable from 0.6 V to 3.3 V in precise 12.5 mV steps. This allows real-time adjustment of core voltages for application processors or ISPs during workload changes - a capability confirmed in the official onsemi datasheet and essential for optimizing power versus performance trade-offs in mobile SoCs.
What is the typical output noise specification for the LDOs in the NCP6922CCMTTXG?
The LDOs in the NCP6922CCMTTXG deliver 50 µVrms typical output noise at rated 150 mA load, measured across 10 Hz–100 kHz bandwidth. This ultra-low noise level is verified in the onsemi characterization report and directly supports noise-sensitive analog circuits such as CMOS image sensors and high-fidelity audio codecs - where higher noise would manifest as visible banding or audible hiss.
Is the NCP6922CCMTTXG pin-compatible with the NCP6922CBMTTXG?
Yes, the NCP6922CCMTTXG and NCP6922CBMTTXG share identical pinout, package (WQFN-20), electrical specifications, and functional behavior - differing only in internal factory programming of default I²C register values. Both parts operate identically in system-level designs, and no PCB or firmware changes are required when substituting one for the other in production.
What thermal management features does the NCP6922CCMTTXG include?
The NCP6922CCMTTXG integrates thermal shutdown protection that disables all regulators when die temperature exceeds 150 °C, and resumes operation after cooling below 135 °C hysteresis. Its 4×4 mm WQFN-20 package includes an exposed thermal pad, which - when soldered to a dedicated PCB copper pour - reduces junction-to-board thermal resistance to 35 °C/W, ensuring reliable operation at full 800 mA DC-DC load in ambient temperatures up to 85 °C.
