Product details
Overview
MIC23150-SYMT-TR from Micrel is a 4MHz synchronous buck regulator delivering 2A output at fixed 3.3V, featuring HyperLight Load® mode for ultra-high light-load efficiency (87% at 1mA) and ultra-fast transient response-designed specifically for powering processor cores in space-constrained portable electronics.
For engineers reviewing the MIC23150-SYMT-TR datasheet, MIC23150-SYMT-TR pinout, MIC23150-SYMT-TR application, or MIC23150-SYMT-TR equivalent, key selection criteria include its 23µA quiescent current, 14mVpp ripple in HyperLight Load mode, 8-pin 2mm × 2mm Thin DFN package, and compatibility with 0.47µH inductors and 2.2µF ceramic output capacitors.
Technical Context
The MIC23150-SYMT-TR implements a proprietary minimum-on/off-time control architecture enabling seamless transition between discontinuous conduction mode (PFM) below ~120mA and continuous conduction mode (PWM) at 4MHz above that threshold. Its integrated PMOS/NMOS synchronous switch pair eliminates external diode losses.
Feedback is sensed via dedicated SNS pin with Kelvin connection to VOUT, while AGND and PGND are physically separated to minimize noise coupling between analog control circuitry and high-current power paths-critical for maintaining ±2.5% output voltage accuracy across load and line variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V - eliminates external resistor divider, reduces BOM count and layout sensitivity. |
| Max Output Current | 2A continuous - supports core rails of application processors and SoCs in handheld devices. |
| Switching Frequency | 4MHz in PWM mode - enables use of sub-1µH inductors and <1mm solution height. |
| Quiescent Current | 23µA typical - extends battery life in always-on subsystems such as GPS or Wi-Fi standby. |
| Output Ripple | 14mVpp in HyperLight Load® mode - maintains clean supply for noise-sensitive RF/analog blocks without large bulk capacitance. |
| Shutdown Current | 0.01µA - ensures near-zero drain during system sleep states. |
| Input Voltage Range | 2.7V to 5.5V - compatible with single-cell Li-ion (3.0–4.2V), USB 5V, and multi-cell alkaline inputs. |
Pinout & Package
Package: 8-pin 2mm × 2mm Thin DFN (TDFN), exposed thermal pad, RoHS-compliant NiPdAu lead finish, halogen-free mold compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 - SW | Power Switch Node | Connects directly to inductor; carries high dv/dt switching waveform-requires short, low-inductance routing away from sensitive nodes. |
| 3 - EN | Enable Input | Logic-compatible input (0.5–1.2V threshold); pulls device into 0.01µA shutdown state when low; must not float. |
| 4 - SNS | Voltage Sense Feedback | Kelvin-sense connection to VOUT near output capacitor-rejects PCB trace IR drop for ±2.5% regulation accuracy. |
| 5 - AGND | Analog Ground Reference | Reference for error amplifier and bias circuits; must tie to star ground point shared with CIN/COUT/PGND for stability. |
| 6, 7 - VIN | Power Input Supply | Accepts 2.7–5.5V; requires ≥2.2µF ceramic bypass capacitor placed adjacent to pins 6/7 and PGND. |
| 8 - PGND | Power Ground Return | High-current return path for internal MOSFETs; separate low-impedance loop from AGND to prevent noise injection. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRYT | 3MHz, 2A, fixed 3.3V; 18µA IQ; no HyperLight Load®-uses standard PFM/PWM auto-mode. | Lacks ultra-fast transient response; higher 25mVpp ripple in light load; requires larger output cap for same stability. | Preferred where cost sensitivity outweighs ripple/transient requirements; pinout incompatible-different package (6-pin WSON). |
| RT8059GJ6 | 3MHz, 2A, adjustable VOUT; 25µA IQ; includes enable and power-good; no proprietary light-load mode. | Requires external feedback resistors; lacks integrated sense pin-lower accuracy under PCB IR drop; needs 4.7µF min COUT. | Chosen when design flexibility (adjustable output) or power-good signaling is required; not drop-in-different pin assignment and layout rules. |
Compared with TPS62231DRYT and RT8059GJ6, the MIC23150-SYMT-TR delivers superior light-load efficiency and lower output ripple without external compensation, but requires strict adherence to AGND/PGND separation and Kelvin SNS routing-making it optimal for high-density, battery-critical portable designs where performance justifies layout discipline.

FAQ
What is the output voltage of the MIC23150-SYMT-TR?
The MIC23150-SYMT-TR provides a fixed 3.3V output voltage-no external feedback resistors are required. This version is factory-trimmed for ±2.5% accuracy over –40°C to +125°C junction temperature, and its SNS pin enables Kelvin sensing to maintain regulation accuracy despite PCB trace resistance.
Does the MIC23150-SYMT-TR support automatic mode switching between PFM and PWM?
Yes-the MIC23150-SYMT-TR uses Micrel's proprietary HyperLight Load® architecture to automatically transition between pulse-frequency modulation (PFM) at light loads (<120mA) and fixed-frequency 4MHz PWM at heavier loads. This ensures peak efficiency of 93% in CCM and 87% at 1mA without external mode control.
What is the minimum recommended output capacitor for the MIC23150-SYMT-TR?
The MIC23150-SYMT-TR is designed to operate stably with a minimum 2.2µF X5R/X7R ceramic output capacitor. Using smaller values risks instability and increased ripple; larger values (e.g., 4.7µF) reduce output ripple and improve transient response but increase solution size and cost.
Can the MIC23150-SYMT-TR be used with a 0.47µH inductor?
Yes-the MIC23150-SYMT-TR explicitly supports inductors as low as 0.47µH, enabling ultra-compact designs with total solution height under 1mm. A 0.47µH inductor also yields the fastest load transient response, though it increases peak inductor current and requires careful saturation current rating verification.
What protection features are integrated into the MIC23150-SYMT-TR?
The MIC23150-SYMT-TR integrates thermal shutdown (160°C activation with 20°C hysteresis), cycle-by-cycle current limiting (2.2–3.4A), undervoltage lockout (2.55V typical turn-on), and soft-start (115µs). These functions protect both the IC and downstream circuitry during fault conditions without requiring external components.
