Product details
Overview
P9120-00NBGI from Integrated Device Technology is a triple-channel synchronous step-down power management IC with integrated high- and low-side MOSFETs, delivering 2A (Buck1), 2A (Buck2), and 3A (Buck3) output currents from a 2.7–5.5V input. It supports factory-programmable output voltages (0.8–3.4V), 2MHz switching frequency, and dual-mode operation for Buck3 (buck or switch configuration). It is used in SSD power management, portable gaming, and USB-powered low-power systems.
For engineers reviewing the P9120-00NBGI datasheet, P9120-00NBGI pinout, P9120-00NBGI application, or P9120-00NBGI equivalent, this page provides verified technical context, validated pin functions, confirmed thermal and electrical specifications, and real-world sequencing behavior across all four operational modes - including cold-boot, standby, and DevSlp transitions.
Technical Context
The P9120-00NBGI implements three independent buck regulators sharing a common 2MHz PWM/PFM control architecture, with programmable slope compensation per channel and OTP-configurable transconductance/bandwidth settings. Each channel features dedicated power-ground pins (PGND1/2/3), separate input rails (PVIN1/2/3), and individual feedback (FB1/2/3) and switch-node (LX1/2/3) terminals.
Its functional flexibility stems from VINSEL-controlled mode selection for Buck3 (buck vs. switch), DEVSLPIN-governed sleep entry/exit, and four OTP-programmable regulator control modes - including individual enable, master-enable sequencing, and SSD-optimized cold-boot with SOCREADY coordination. Power-good (PORB) and power-on-reset generation are integrated and configurable via OTP.
Key Specifications

| Buck1 / Buck2 Output Current | 2A continuous - sufficient for core logic or memory rails in portable SSDs and set-top boxes |
| Buck3 Output Current | 3A continuous in buck mode; 2.4A in switch mode - enables high-current I/O or interface rail support |
| Switching Frequency | 2MHz ±5% - allows use of compact 1.0µH inductors and reduces output capacitor size |
| Operating Temperature | −40°C to +85°C ambient - qualified for industrial and consumer embedded environments |
| Quiescent Current (Sleep) | <1μA with DEVSLPIN floating - extends battery life in always-on portable devices |

Pinout & Package
Package: QFN-24, 4mm × 4mm × 0.75mm, exposed pad (EP), 0.5mm pitch - optimized for thermal dissipation and PCB area efficiency in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VINSEL (Pin 4) | Mode select input | Determines Buck3 function: LOW = buck regulator; HIGH = switch-mode output with UVLO threshold shift |
| DEVSLPIN (Pin 5) | Sleep control input | Floating or HIGH = ultra-low-power sleep mode (<1μA); LOW = active regulation |
| FB1/FB2/FB3 (Pins 6,13,18) | Feedback inputs | Resistive divider inputs for precise output voltage regulation (0.8–3.4V range, 25mV LSB) |
| LX1/LX2/LX3 (Pins 7,12,20–21) | Switch-node outputs | Connect directly to inductor; drive internal high-/low-side FETs at 2MHz switching frequency |
| PGND1/PGND2/PGND3 (Pins 8,11,19) | Power ground returns | Separate ground paths per channel minimize cross-regulator noise coupling and improve PSRR |
| VGND (Pin 1) | Analog ground reference | Reference for internal bias circuitry and feedback comparators; must be routed separately from PGND |
| EP | Exposed thermal pad | Must be soldered to PCB ground plane with 3×3 thermal vias to achieve θJA = 40°C/W |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-output PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum continuous output current supported by each channel of the P9120-00NBGI?
The P9120-00NBGI delivers 2A continuously on Buck1 and Buck2, and 3A continuously on Buck3 in buck mode (TJ < 115°C). In switch mode, Buck3 supports 2.4A continuous output. These ratings are validated with 1.0µH inductors and proper thermal layout using the EP ground pad and thermal vias - exceeding typical 2A/2A/2.5A competitors in the same QFN-24 footprint.
How does the VINSEL pin affect the operation and UVLO behavior of the P9120-00NBGI?
The VINSEL pin (Pin 4) configures Buck3: LOW selects buck regulator mode (UVLO rising threshold = 3.0V), HIGH selects switch-mode output (UVLO rising threshold = 4.4V). This dual-threshold behavior ensures reliable startup under both 3.3V and 5V input conditions. The P9120-00NBGI datasheet confirms these values in Table 4 and Figure 1, and the pin's logic level directly determines FB3 and LX3 functional roles.
Can the P9120-00NBGI support power sequencing required for SSD controllers like those compliant with JEDEC UFS?
Yes - the P9120-00NBGI supports cold-boot sequencing (Mode 1) with SOCREADY handshake, COLDBOOT assertion, and DEVSLPRLY coordination, as documented in Figures 3–5 and Table 9. This exact sequence meets JEDEC UFS v2.1 power-up timing requirements for NAND flash, controller, and interface rails. The P9120-00NBGI implements this natively via OTP configuration without external logic.
What is the minimum quiescent current achievable with the P9120-00NBGI, and under what conditions?
The P9120-00NBGI achieves <1μA quiescent current in sleep mode when DEVSLPIN is left floating (internally pulled to ~1.5V), VREF is disabled via OTP, and all bucks are off. This value is measured per Table 4 and Figure 19, and is critical for battery-backed applications such as portable SSDs in standby. Pulling DEVSLPIN to VIN increases leakage to 10–18μA.
Does the P9120-00NBGI require external components for stable operation, and if so, what are the minimum requirements per channel?
Yes - each buck channel requires three external components: a 10µF (or greater) X7R ceramic input capacitor at PVINx, a 1.0µH shielded inductor at LXx, and a 10µF (Buck1/Buck2) or 20µF (Buck3) X7R output capacitor at VOUTx. The P9120-00NBGI datasheet specifies these in Section "Component Selection" (Page 13) and validates them with Toko 1239AS-H-1R0M inductor and 10V-rated capacitors.
