Product details
Overview
NCP6360FCCT2G from onsemi is a PWM synchronous step-down DC-DC converter optimized for RF power amplifier (PA) biasing in 3G/4G mobile devices powered by single-cell Li-ion batteries. It delivers up to 800 mA, supports 0.6 V–3.4 V analog-adjustable output via VCON pin (gain = 2.5×), and operates at 6 MHz with PFM/PWM auto-mode switching for dynamic efficiency optimization during voice calls or roaming.
For engineers reviewing the NCP6360FCCT2G datasheet, pinout, applications, or equivalent options, key selection criteria include its 1.5 × 1.0 mm WLCSP-6 package, 30 µA quiescent current in PWM mode, thermal shutdown at 155°C, integrated high-side/low-side MOSFETs (RONHS = 168 mΩ, RONLS = 78 mΩ), and VOUT accuracy of ±3% over temperature and load.
Technical Context
The NCP6360FCCT2G implements voltage-mode control with fully integrated synchronous rectification, eliminating external diodes or discrete switches. Its analog VCON input directly sets output voltage (VOUT = 2.5 × VCON), enabling real-time PA efficiency tuning during RF envelope variations.
It autonomously transitions between PWM (fixed 6 MHz, CCM), PFM (variable frequency, DCM), sleep (VCON < 75 mV), and shutdown (EN low or PVIN < 2.35 V) modes - each with distinct current consumption (30 µA / 25 µA / 0.7 µA) and transient response profiles (≤50 mVpk line/load transients).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - compatible with single-cell Li-ion battery discharge profile without external regulation. |
| Output Voltage Range | 0.6 V to 3.4 V - set dynamically via analog VCON pin (0.24–1.36 V), enabling closed-loop PA efficiency control. |
| Switching Frequency | 6 MHz (±10%) - enables ultra-small passive footprint (0.47 µH inductor, 4.7 µF output cap) and minimizes EMI in RF-sensitive layouts. |
| Max Output Current | 800 mA in PWM mode - sufficient for mid-power RF PAs in smartphones and phablets. |
| Quiescent Current | 30 µA (PWM no-load) - extends battery life during standby and light-load PA operation. |
| Thermal Protection | 155°C shutdown with 35°C hysteresis - prevents irreversible damage under sustained high-power PA bias conditions. |
| VOUT Accuracy | ±3% (typical) - ensures precise PA bias voltage tracking across temperature and load for consistent RF linearity. |
Pinout & Package
The NCP6360FCCT2G is housed in a 1.5 mm × 1.0 mm, 0.5 mm pitch, 6-bump WLCSP (Wafer-Level Chip Scale Package), Case 568AN, with bottom-side solder bumps for direct PCB mounting and minimal footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (A1) | Enable Input | Active-high logic control with internal pull-down; initiates soft-start (140 µs) and disables all circuitry when low. |
| PVIN (A2) | Power Input | Main DC input (2.7–5.5 V); requires local 10 µF + 1 µF ceramic decoupling to minimize switching noise injection. |
| VCON (B1) | Analog Control Input | Directly programs VOUT = 2.5 × VCON (0.24–1.36 V → 0.6–3.4 V); must be shielded from RF noise to prevent PA bias instability. |
| SW (B2) | Switch Node | High-current switching node connecting internal HS/LS FETs to inductor; layout critical for EMI and efficiency. |
| FB (C1) | Feedback Input | Connects to output capacitor positive terminal; senses regulated VOUT for error amplifier comparison against internal reference. |
| PGND (C2) | Power Ground | High-switching-current return path; requires dedicated low-impedance ground plane to avoid noise coupling into FB/VCON. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power amplifier biasing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62865DRLR | Higher 2-A output, 2.5-V to 5.5-V input, but fixed 0.6-V to 3.3-V VOUT range; no analog VCON interface - uses I²C or resistor programming. | Suitable for systems with digital control architecture (e.g., baseband processor I²C bus), not analog envelope tracking. | Select when digital configurability and higher current headroom outweigh need for analog VCON-based dynamic efficiency tuning. |
| RTQ2132BWGE | Supports 0.6–3.3 V output via external resistor divider; 1.2-A rating; 2.5–5.5 V input; no VCON pin - uses standard feedback network. | Applicable where PA bias is static or adjusted infrequently; lacks real-time analog control required for envelope tracking. | Choose for cost-sensitive designs needing robust 1.2-A capability and simplified layout, but unable to support dynamic VOUT modulation. |
Compared with TPS62865DRLR and RTQ2132BWGE, the NCP6360FCCT2G uniquely provides true analog VCON-based output control (VOUT = 2.5 × VCON) in a 1.5 × 1.0 mm WLCSP - making it the only option among the three that enables seamless integration with RF envelope detectors and analog DACs for real-time PA efficiency optimization.

FAQ
What is the primary function of the VCON pin on the NCP6360FCCT2G?
The VCON pin on the NCP6360FCCT2G is an analog input that directly controls the output voltage according to VOUT = 2.5 × VCON. With VCON ranging from 0.24 V to 1.36 V, it enables precise, real-time adjustment of the RF power amplifier's supply voltage - allowing dynamic efficiency optimization during varying signal conditions such as roaming or changing channel quality. This feature is central to the NCP6360FCCT2G's role in extending talk time in mobile devices.
Does the NCP6360FCCT2G require external MOSFETs or diodes?
No, the NCP6360FCCT2G integrates both high-side and low-side synchronous MOSFETs (RONHS = 168 mΩ, RONLS = 78 mΩ), eliminating the need for external power switches or freewheeling diodes. Its fully integrated synchronous buck architecture simplifies design, reduces BOM count, and improves efficiency - especially at light loads where asynchronous solutions suffer from diode conduction losses. The NCP6360FCCT2G only requires external passive components: an inductor, input/output capacitors, and optional compensation elements.
What package type and dimensions does the NCP6360FCCT2G use?
The NCP6360FCCT2G uses a Wafer-Level Chip Scale Package (WLCSP-6) with mechanical dimensions of 1.5 mm × 1.0 mm × 0.592 mm and a 0.5 mm bump pitch (Case 568AN). This ultra-compact, bottom-terminal package enables minimal PCB footprint (<1.5 mm²) and low-profile integration - essential for thin mobile devices and dense RF front-end layouts. Its thermal resistance (RθJA = 85°C/W) is characterized on a 4-layer PCB, and thermal vias are recommended for optimal heat dissipation.
How does the NCP6360FCCT2G manage efficiency across varying load conditions?
The NCP6360FCCT2G automatically transitions between PWM (6 MHz, continuous conduction mode) at medium-to-heavy loads and PFM (pulse frequency modulation, discontinuous mode) at light loads - achieving ≥82% efficiency at 10 mA and ≥94% at 300 mA. In PWM mode, it delivers up to 800 mA with 30 µA quiescent current; in PFM, IQ drops further to optimize battery life during standby or low-SNR operation. The NCP6360FCCT2G also enters sleep mode (<25 µA) when VCON falls below ~75 mV, providing granular efficiency control aligned with RF PA demand.
What protection features are built into the NCP6360FCCT2G?
The NCP6360FCCT2G includes under-voltage lockout (UVLO) with 2.35 V turn-on threshold and 100 mV hysteresis, thermal shutdown at 155°C (with 35°C hysteresis), peak current limiting (1.5 A high-side), and short-circuit protection via cycle-by-cycle current sensing. These safeguards ensure robust operation during battery voltage sag, thermal overload, or abnormal load conditions - preventing damage to the IC or downstream RF circuitry. All protections are fully integrated and require no external components to function.
