General Description
The HT7A4016 is a controller IC that includes the necessary features to
implement off-line or DC-DC current mode control schemes with a minimal
external parts count. Internal circuits include a specially designed Mixed-
Mode/Analog Interface for multifunction and multi-topology control schemes
(DC-DC Buck/Boost, Off-line AC-DC), a trimmed oscillator for precise duty-
cycle control under voltage lockout with a start-up current of less than
0.5mA, a wide temperature range, precise voltage reference, internal Slope
Compensation and Leading-Edge Blanking. The HT7A4016 features basic system
protection functions such as Cycle-by-Cycle Current Limiting and Under Voltage
Lock-Out (UVLO).
A Multi-Function Pin can be used as a dimming function for LED driving, and as
a primary feedback control for Primary-Side Feedback AC-DC applications.
Feature
• High Performance, Low Cost Current Mode PWM Controller especially designed
for Energy Star 2.0
• Very Low Startup Current (<20μA) and Operating Current
• High-Voltage CMOS Process with Excellent ESD protection (>3KV)
• ±5% Trimmed Oscillator for Precise Frequency Control
• LEB (Leading-Edge Blanking) on CS Pin
• Internal Slope Compensation
• Programmable Switching Frequency
• Internally Trimmed Reference with UVLO (Under Voltage Lockout)
• Cycle-by-Cycle Current Limiting
