Product details
Overview
MIC23150-GYMT-TR from Micrel is a 4MHz synchronous buck regulator delivering 2A output current with HyperLight Load® mode, designed for core voltage regulation in portable processors. It operates from 2.7V–5.5V input, provides fixed 1.8V output, achieves 93% peak efficiency and 23µA quiescent current, and uses a compact 2mm × 2mm Thin DFN package-ideal for space-constrained mobile power rails.
For engineers reviewing the MIC23150-GYMT-TR datasheet, MIC23150-GYMT-TR pinout, MIC23150-GYMT-TR application, or MIC23150-GYMT-TR equivalent, key selection criteria include light-load efficiency (87% at 1mA), ultra-low output ripple (14mVpp in HyperLight Load mode), thermal shutdown (160°C), and compatibility with 0.47µH inductors and 2.2µF ceramic output capacitors.
Technical Context
The MIC23150-GYMT-TR implements a proprietary minimum-on/off-time control architecture enabling seamless transition between pulse-frequency modulation (PFM) in discontinuous conduction mode (DCM) below ~120mA and fixed 4MHz PWM in continuous conduction mode (CCM). Its integrated PMOS/NMOS synchronous switches eliminate external diode losses and support ultra-fast transient response.
It features dedicated analog ground (AGND) and power ground (PGND) pins to isolate noise-sensitive feedback paths from high-current switching loops, and a precision SNS pin routed directly to the output capacitor for accurate voltage regulation across load and line variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports single-cell Li-ion, USB VBUS, and regulated 3.3V/5V rails without pre-regulation. |
| Output Voltage | Fixed 1.8V - factory-trimmed for processor I/O or memory interface supply with ±2.5% accuracy over temperature and load. |
| Max Output Current | 2A - sufficient for ARM Cortex-A/M cores and LPDDR2/3 I/O domains in handheld devices. |
| Switching Frequency | 4MHz (PWM mode) - enables use of sub-1µH inductors and reduces EMI fundamental frequency above AM band. |
| Quiescent Current | 23µA - minimizes standby power loss in always-on subsystems like GPS or Bluetooth coexistence modules. |
| Output Ripple | 14mVpp (HyperLight Load), 5mVpp (PWM) - allows small 2.2µF X5R/X7R ceramic output capacitors without bulk electrolytics. |
| Shutdown Current | 0.01µA - ensures negligible battery drain during deep sleep states in portable electronics. |
Pinout & Package
Package: 8-pin 2mm × 2mm Thin DFN (TDFN), thermally enhanced with exposed pad (MM footprint), RoHS-compliant NiPdAu lead finish, halogen-free mold compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 - SW | Power switch node | Connects to inductor; carries high dv/dt switching current - requires short, low-inductance routing away from sensitive analog traces. |
| 3 - EN | Logic enable input | Active-high (0.8V threshold); pulls device into 0.01µA shutdown - must be actively driven, not left floating. |
| 4 - SNS | Voltage feedback sense | High-impedance Kelvin connection to VOUT near output capacitor - critical for ±2.5% regulation accuracy under load transients. |
| 5 - AGND | Analog reference ground | Return path for internal error amplifier and bias circuitry - must tie to star ground point separate from PGND loop. |
| 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 for MOSFET switching path - connects to input/output capacitor grounds and inductor ground plane with minimal loop area. |
Key Features
| Feature | Design Value |
|---|---|
| HyperLight Load® mode | Proprietary PFM/PWM hybrid control enabling 87% efficiency at 1mA while maintaining <14mVpp ripple - extends battery life in idle/sleep states. |
| Ultra-fast transient response | Sub-10µs recovery from 0.1A→2A load steps due to adaptive on/off timing - prevents core voltage droop during CPU burst activity. |
| Thermal & current protection | Integrated 160°C thermal shutdown with 20°C hysteresis and cycle-by-cycle current limiting (2.2–3.4A) - eliminates need for external fault management circuitry. |
| Minimal external components | Operates with only one inductor (0.47–2.2µH), one input cap (≥2.2µF), and one output cap (≥2.2µF) - reduces BOM count and PCB area vs. legacy buck solutions. |
| Low-profile solution | Total height <1mm with 2.2µF 0603 output capacitor and 1.0×1.0mm inductor - meets mechanical constraints of ultrathin smartphones and wearables. |

FAQ
What is the output voltage of the MIC23150-GYMT-TR and is it adjustable?
The MIC23150-GYMT-TR provides a fixed 1.8V output voltage, factory-trimmed and non-adjustable. This version is part of Micrel's pin-compatible family where output voltage is set by laser trimming during wafer test - other variants (e.g., MIC23150-CYMT = 1.0V, MIC23150-SYMT = 3.3V) share identical pinout and package but differ only in nominal output. The MIC23150-GYMT-TR does not support external resistor feedback networks.
Does the MIC23150-GYMT-TR require an external compensation network?
No, the MIC23150-GYMT-TR is internally compensated and designed for unconditional stability with 0.47µH–2.2µH inductors and ≥2.2µF X5R/X7R ceramic output capacitors. No external compensation components are needed - simplifying layout and reducing BOM count. Stability is verified across –40°C to +125°C junction temperature and full input/output operating ranges per Micrel's Application Note AN-47.
What is the maximum recommended inductor value for the MIC23150-GYMT-TR?
The MIC23150-GYMT-TR is characterized and guaranteed stable with inductors ranging from 0.47µH to 2.2µH. While larger values (e.g., 4.7µH) may function, they risk violating the minimum off-time constraint in HyperLight Load® mode, causing audible switching noise or reduced light-load efficiency. Micrel's datasheet specifies 2.2µH as the upper limit for guaranteed PFM/PWM transition behavior and transient performance.
How does the MIC23150-GYMT-TR handle thermal overload conditions?
The MIC23150-GYMT-TR integrates thermal shutdown that activates at 160°C junction temperature, latching off until die temperature falls by 20°C hysteresis. During overload, it first engages cycle-by-cycle current limiting (trip point 2.2–3.4A) before thermal shutdown intervenes. This dual-protection scheme prevents damage during sustained overloads or short-circuit events without requiring external thermal sensors or reset circuitry - a key reliability feature confirmed in Micrel's reliability report R-2014-087.
Can the MIC23150-GYMT-TR be used with ceramic capacitors smaller than 2.2µF?
No - Micrel specifies a minimum 2.2µF X5R/X7R ceramic output capacitor for stability and ripple performance. Using smaller values risks violating phase margin requirements, increasing output ripple beyond 14mVpp in HyperLight Load® mode, and degrading transient response. The 2.2µF minimum is validated across all operating conditions including –40°C to +125°C and full 0–2A load range, as documented in the MIC23150-GYMT-TR Electrical Characteristics table.
