What are the key features of MCP1631HV-500E/ST?
- High-speed current-mode PWM control from 3.5 V to 16 V input enables fast response and stable regulation across a wide supply range
- High-voltage (HV) rated design supports direct use on bus rails up to 16 V without additional pre-regulation stages
- 20-pin TSSOP package provides a small PCB footprint with access to comprehensive control and protection signal pins
What is MCP1631HV-500E/ST used for?
The MCP1631HV-500E/ST is designed for power management in battery chargers, LED driver controllers, and DC-DC converters where current-mode PWM control and high-voltage input tolerance are required. Its 3.5 V to 16 V input range makes it compatible with single-cell Li-ion, multi-cell NiMH packs, and 12 V automotive or industrial bus rails. The device is also used in programmable power supplies and lab bench converters requiring precise current-loop regulation.

Frequently Asked Questions
What input voltage range does MCP1631HV-500E/ST support, and which power supply topologies benefit from this range?
The MCP1631HV-500E/ST operates from 3.5 V minimum to 16 V maximum input, with a 5 V nominal supply. This wide range suits buck, boost, and flyback topologies powered from single Li-ion cells (3.7 V), 12 V automotive rails, and 5 V USB power adapters. The 16 V maximum rating provides margin against load dumps and transients common on 12 V automotive and industrial DC buses.
How does current-mode PWM control in MCP1631HV-500E/ST improve converter stability and transient response?
Current-mode PWM control in the MCP1631HV-500E/ST uses inner current feedback to regulate inductor peak current cycle-by-cycle, inherently limiting inductor saturation and short-circuit current. This control scheme reduces the output filter requirements by one order compared to voltage-mode control, improving load-transient response by 2x to 3x and enabling stable operation with smaller output capacitances below 10 µF in compact converter designs.
What is the lead time for MCP1631HV-500E/ST, and how should supply chain managers account for it?
Standard factory lead time for the MCP1631HV-500E/ST is 11 weeks. Supply chain managers should build at least 13 to 14 weeks of safety stock before production ramp-up and consider placing scheduled orders with authorized Microchip distributors to secure inventory. The TSSOP-20 package is industry-standard, so packaging-compatible pin-compatible alternatives may be sourced as a contingency during extended lead-time periods.
What PCB package does MCP1631HV-500E/ST use, and what layout best practices apply to a 16 V current-mode PWM design?
The MCP1631HV-500E/ST is packaged in a 20-pin TSSOP with a 0.65 mm pin pitch. For a 16 V high-speed PWM layout, the current-sense resistor should be placed within 5 mm of the sense pins to minimize noise pickup, and the bootstrap or gate-drive traces must be kept short to reduce ringing. A solid ground plane beneath the IC and low-ESR input decoupling capacitors of at least 10 µF help attenuate switching noise and ensure stable regulation.
